What Is a Spanish Onion?

Have you ever come across different varieties of onions? There are multiple types of onions, and it can be confusing to keep track of them all. One type of onion that people may not know about is the Spanish onion. 

Spanish onions have a fine texture and a yellow peel. They have gained popularity because they have a mild distinctive flavor, and many people find it subsequently sweet to consume raw. 

If you want to know more about Spanish onions and their substitutes, read on since for some interesting facts about them. 

What Are Spanish Onions?

Spanish onions have their root in the Mediterranean and are generally grown in hot and muggy conditions. They are sometimes mistaken for typical yellow onions due to their papery yellow exterior and white-yellow bulb. Spanish onions are typically sold alongside regular yellow onions at many supermarkets.

Because of their unusually low sulfur concentration and high sugar content, Spanish onions are distinctive. This is because the low sulfur content gives them a very subtle and light taste.

However, when cooking them, you must know that they have some sweet notes in them Because of this, overcooking makes it incredibly simple to lose flavor. 

For a quick and easy meal, try them raw in a salad or a sandwich. Similarly, a few grilled slices on a burger patty would provide a nice touch of sweetness.

Or, if you’d like to add extra sweetness to your pasta, try substituting Spanish onions for the red onion and cooking them in a little olive oil.

Likewise, these bright Spanish onions should not be kept in the refrigerator. Compared to sweet onions, they deteriorate more quickly in the fridge.

Regular vs. Spanish Onions

Spanish and yellow onions are both yellow, making them easy to confuse. The exterior of Spanish onions is covered in a thin, yellowish peel, and they can grow quite large.

These two onions seem extremely similar, yet their flavors are very different. Regular onions and Spanish onions are very distinct from one another because they both develop various textures and tastes.

White onions are softer and sweeter than yellow onions. On the other hand, Spanish onions, which can be either white or yellow, are sweeter and gentler than yellow and white onions.

On the contrary, yellow onions, as compared to white onions, are more temperate and sweeter.

Compared to yellow and white onions, Spanish onions are frequently eaten uncooked.

Last but not least, remember that Spanish onions don’t last as long on the pantry shelf as white or yellow ones.

Does Chopping Spanish Onions Make You Cry?

As stated earlier, Spanish onions contain more sugar and less sulfur than regular onions and are least likely to bring tears to your eyes. Even though this is often true, it is not always the case. This depends on the soil conditions in which each onion was produced.

But fortunately, you can do a few things to lessen or stop sobbing when chopping: Wearing safety or swimming goggles, lighting a candle beside your cutting board, turning on the vent hood above your stove, freezing the vegetables in advance, or soaking them in ice water prior chopping are all options.

If none of those solutions works, then at the very least, get yourself a good knife.

They can even be used as a replacement for red onions. However, doing so will cause the dish to take on a somewhat sweeter flavor.
