What are Spanish onions and how do they differ from other types of onions?
Spanish onions are a type of sweet onion that originates from Spain. They are known for their sweet and mild flavor, making them a popular choice for a variety of dishes, from salads to sauces. One of the main differences between Spanish onions and other types of onions is their sweetness level.

How do I choose the best Spanish onions for cooking?
When choosing Spanish onions, there are several factors to consider to ensure you select the best ones for your recipe.

Next, check the skin of the onion, which should be dry and papery, with no visible signs of mold or mildew. Finally, give the onion a sniff – a sweet, mild aroma is a good indication of a fresh and flavorful Spanish onion.
In addition to these physical characteristics, it’s also important to consider the color and shape of the onion.
