Canned tomatoes are a pantry staple for countless home cooks and professional chefs alike. They offer convenience, affordability, and a concentrated burst of tomato flavor, making them ideal for everything from hearty pasta sauces to comforting soups and stews. But have you ever stopped to wonder exactly how much “tomato” you’re getting in that can? The answer isn’t always straightforward, as it depends on the type of canned tomatoes you’re using. Let’s unpack the secrets of canned tomato measurements and unlock the full potential of this versatile ingredient.
Understanding Canned Tomato Varieties and Their Liquid Content
Before we delve into cup conversions, it’s essential to understand the different types of canned tomatoes commonly available. Each type has a varying degree of tomato solids and liquid, impacting the final cup measurement.
Diced Tomatoes: Cubed Perfection
Diced tomatoes are exactly what they sound like: tomatoes that have been cut into small, uniform cubes. They’re often packed in tomato juice, which contributes to the overall volume. The diced nature of these tomatoes means they typically have a higher solid content compared to other varieties.
Crushed Tomatoes: A Rustic Texture
Crushed tomatoes offer a more rustic texture, ideal for sauces where you want a bit of visible tomato. They can range from coarsely crushed to almost a purée. Like diced tomatoes, they are also packed in tomato juice or purée.
Whole Peeled Tomatoes: The Versatile Foundation
Whole peeled tomatoes are, well, whole tomatoes that have had their skins removed. They’re often packed in tomato juice or purée and can be used whole, chopped, or crushed, offering maximum versatility.
Tomato Paste: Concentrated Flavor Bomb
Tomato paste is highly concentrated tomato purée that has been cooked down to remove most of the moisture. This process results in a thick, intensely flavored paste. It’s used to add depth and richness to sauces, stews, and other dishes. Because of its density, its cup conversion is quite different from other canned tomato products.
Tomato Purée: A Smooth Base
Tomato purée is cooked and strained tomatoes, resulting in a smooth, consistent texture. It’s less concentrated than tomato paste but more concentrated than crushed tomatoes. This makes it a good choice for sauces where you want a smooth base.
The Great Cup Conversion: How Much Tomato is in Each Can?
Now, let’s get to the heart of the matter: how many cups of tomatoes are actually in a can? Keep in mind that these are general guidelines, and slight variations can occur between brands.
Standard Can Sizes and Their Cup Equivalents
The most common can sizes for tomatoes are:
- 14.5-ounce can: This size typically holds about 1 ¾ cups (approximately 414 ml).
- 15-ounce can: Slightly larger, this can contains roughly 1 ¾ cups (approximately 443 ml). This is almost identical to the 14.5-ounce can.
- 28-ounce can: This is the workhorse of the canned tomato world. It holds approximately 3 ½ cups (approximately 828 ml).
- 10-ounce can (Tomato Paste): This smaller can of concentrated tomato paste usually contains around 1 ⅓ cups (approximately 315 ml).
- 6-ounce can (Tomato Paste): The smaller version of tomato paste provides about ¾ cup (approximately 177 ml).
Factoring in the Liquid: Solid vs. Liquid Measurement
It’s crucial to remember that the cup measurement includes both the solid tomato pieces and the liquid they’re packed in. If a recipe calls for “drained” diced tomatoes, you’ll need to account for the liquid you’re discarding. Draining the tomatoes reduces the overall cup measurement slightly. For example, a 14.5-ounce can of diced tomatoes, when drained, might yield closer to 1 ½ cups of solid tomato pieces.
Tomato Paste: A Different Beast
Tomato paste is unique because of its concentrated nature. A tablespoon of tomato paste packs a significant punch of tomato flavor. While a 6-ounce can contains about ¾ cup, it’s important to remember that you’ll often use it in much smaller quantities than other canned tomato products.
Practical Tips for Using Canned Tomatoes in Recipes
Knowing the cup conversions for canned tomatoes is essential, but understanding how to use them effectively in recipes is even more important.
Adjusting Recipes Based on Can Size
Many recipes call for specific amounts of canned tomatoes. If you don’t have the exact size called for, you can easily adjust by using the cup conversions we’ve discussed. For example, if a recipe calls for 3 cups of crushed tomatoes and you only have a 28-ounce can (3 ½ cups), you can simply use a little less from the can.
Enhancing Flavor with Different Tomato Varieties
Experiment with different types of canned tomatoes to achieve the desired flavor and texture in your dishes. Diced tomatoes add a chunky texture, crushed tomatoes provide a rustic feel, and tomato purée creates a smooth base. Combining different varieties can also add complexity to your sauces and stews.
Tips for Draining and Measuring
When a recipe calls for drained tomatoes, use a fine-mesh sieve to remove the excess liquid. Gently press down on the tomatoes to extract as much liquid as possible. After draining, measure the tomatoes to ensure you have the correct amount.
Tomato Paste Alternatives: When You’re Running Low
If you find yourself short on tomato paste, there are a few substitutes you can use. Tomato purée can be reduced on the stovetop to thicken it and intensify the flavor. You can also use a small amount of tomato sauce, although it will be less concentrated than tomato paste. Sun-dried tomato paste is another alternative that will provide a rich and concentrated flavor.
You can adjust the amount to achieve the desired intensity.
The Art of Roasting Canned Tomatoes
Roasting canned tomatoes can intensify their sweetness and add a smoky flavor. Simply spread the tomatoes on a baking sheet, drizzle with olive oil, and roast at 400°F (200°C) for 20-30 minutes. Roasted canned tomatoes are excellent in sauces, soups, and even as a topping for bruschetta.
This method works particularly well with whole peeled tomatoes.
Beyond the Basics: Exploring the World of Canned Tomato Products
Canned tomatoes are just the beginning. There’s a whole world of tomato-based products to explore, each with its own unique flavor profile and uses.
Canned Tomato Sauce: A Versatile Base
Canned tomato sauce is a smooth, cooked tomato product that can be used as a base for various dishes. It’s typically seasoned with salt and other spices, making it a convenient option when you’re short on time.
Canned Tomato Juice: A Refreshing Drink and Cooking Ingredient
Canned tomato juice is a refreshing beverage and a versatile ingredient in cocktails and savory dishes. It can be used as a base for soups, stews, and sauces. It is a great source of Vitamin C.
Canned Stewed Tomatoes: Flavorful and Convenient
Stewed tomatoes are canned tomatoes that have been cooked with other vegetables and seasonings, such as onions, peppers, and celery. They offer a convenient way to add flavor and texture to stews, soups, and casseroles.
Canned Sun-Dried Tomatoes: An Intense Flavor Boost
Although often found in jars packed in oil, sun-dried tomatoes are also available canned, offering a concentrated burst of tomato flavor. They are excellent in pasta dishes, salads, and as a topping for pizzas.
Storing Canned Tomatoes: Keeping Your Pantry Prepared
Proper storage is crucial for maintaining the quality and safety of canned tomatoes.
Unopened Canned Tomatoes: Shelf Life and Storage Tips
Unopened canned tomatoes can be stored in a cool, dry place for up to two years. Avoid storing them in damp or humid environments, as this can cause the cans to rust. Always check the “best by” date on the can before using.
Opened Canned Tomatoes: Refrigeration and Usage
Once you’ve opened a can of tomatoes, transfer any unused portion to an airtight container and refrigerate immediately. Use the refrigerated tomatoes within 5-7 days for optimal quality.
It is important not to store opened canned tomatoes in the opened can.
Freezing Canned Tomatoes: A Long-Term Solution
If you have leftover canned tomatoes that you won’t use within a week, you can freeze them. Transfer the tomatoes to a freezer-safe container, leaving some headspace for expansion. Frozen canned tomatoes may lose some of their texture, but they’ll still be suitable for use in sauces, soups, and stews.
Conclusion: Mastering the Art of Canned Tomato Conversions
Canned tomatoes are a kitchen essential, and understanding their cup conversions is key to successful cooking. By knowing how much “tomato” is in each can and how to adjust recipes accordingly, you can confidently create delicious and flavorful dishes every time. So, the next time you reach for a can of tomatoes, you’ll be armed with the knowledge to unlock its full potential. Happy cooking!
How many cups are typically in a standard 14.5-ounce can of diced tomatoes?
A standard 14.5-ounce can of diced tomatoes generally contains about 1 ¾ cups of diced tomatoes. However, this can vary slightly depending on the specific brand and how densely packed the tomatoes are in the can. Always check the product label for the manufacturer’s stated serving size and volume information for the most accurate measurement.
Keep in mind that the liquid content in the can contributes to the overall weight and volume. When measuring for a recipe, it’s best to drain the diced tomatoes before measuring if the recipe specifically calls for “drained diced tomatoes.” Otherwise, include both the solids and the liquid for the full tomato flavor and moisture.
What is the cup equivalent of a 28-ounce can of crushed tomatoes?
A 28-ounce can of crushed tomatoes typically yields approximately 3 ½ cups. This measurement provides a good starting point for most recipes, but slight variations can occur based on the brand and the consistency of the crushed tomatoes. Always measure for accuracy if the recipe requires a precise amount.
It’s important to note that some recipes might call for “crushed tomatoes in puree.” If that is the case, be aware that the puree will add to the overall volume. If the recipe only calls for plain crushed tomatoes, consider draining some of the excess liquid if the consistency seems too thin after measuring.
How many cups are in a 6-ounce can of tomato paste?
A 6-ounce can of tomato paste contains approximately ¾ of a cup. Tomato paste is highly concentrated, so a small amount can add a significant amount of tomato flavor to your dishes. Always check the recipe requirements, as using too much tomato paste can overpower other ingredients.
When measuring tomato paste, use a measuring cup or spoon that is specifically designed for measuring small amounts. Level off the paste to ensure an accurate measurement. If the recipe calls for a partial amount of tomato paste, you can store the remainder in an airtight container in the refrigerator for later use.
How does the liquid in a can of tomatoes affect volume measurements?
The liquid in canned tomatoes contributes to the overall volume, so when a recipe calls for “drained” tomatoes, the cup measurement will be less than if you include the liquid. The amount of liquid can vary between brands and types of canned tomatoes (e.g., whole peeled, diced). Always read the recipe carefully to determine if draining is required.
If you’re unsure whether to drain the tomatoes, consider the desired consistency of the final dish. If you want a thicker sauce or stew, draining the tomatoes may be beneficial. If you want a more liquid or broth-like consistency, including the liquid is perfectly fine. The liquid is often rich in flavor and nutrients, so it’s generally a good idea to incorporate it unless otherwise specified.
Can I substitute different types of canned tomatoes based on cup measurements?
Yes, you can generally substitute different types of canned tomatoes (e.g., whole peeled, crushed, diced) based on their equivalent cup measurements. However, keep in mind that each type has a different texture and consistency, which can affect the final result of your recipe. For example, using whole peeled tomatoes instead of crushed tomatoes will require extra steps to break down the tomatoes.
When substituting, consider the intended use of the tomatoes. If the recipe calls for a smooth sauce, crushed tomatoes or tomato puree would be better choices than diced tomatoes. If you need a chunkier texture, diced tomatoes or whole peeled tomatoes that you break down yourself would be more suitable.
What’s the best way to store leftover canned tomatoes after opening?
Once opened, leftover canned tomatoes should be transferred to an airtight container and stored in the refrigerator. It is important to avoid storing the tomatoes in the opened can, as the acidic tomatoes can react with the metal lining, potentially affecting the taste and quality. Glass or plastic containers work well for storing leftover tomatoes.
Leftover canned tomatoes typically last for 5-7 days in the refrigerator if stored properly. Before using, check for any signs of spoilage, such as a foul odor or discoloration. You can also freeze leftover canned tomatoes for longer storage. Simply transfer them to a freezer-safe container and freeze for up to 2-3 months.
Does the size of the diced tomatoes affect the cup measurement?
Yes, the size of the diced tomatoes can slightly affect the cup measurement. Larger diced tomatoes will result in fewer tomatoes fitting into a cup compared to finely diced tomatoes. The difference is usually minimal, but it’s something to keep in mind if you’re aiming for precise measurements, especially for delicate recipes.
Ultimately, the most important factor is the overall weight of the can and the liquid content. While the size of the dice can influence the packed density, the total volume provided on the can’s label is a more reliable indicator of the amount of tomato you’re getting. Use the can’s stated volume for the most accurate results.
