Frequently Asked Questions

Why do chefs prefer yellow onions over other types?
Chefs often go for yellow onions because of their robust flavor. These onions become sweeter as they cook, making them incredibly versatile in the kitchen. From soups and stews to sautés, their ability to blend well with other ingredients and enhance flavors is unmatched.
What's the best way to store yellow onions?
Keep them in a cool, dry place with plenty of air circulation. Avoid storing them near potatoes, as this can cause both to spoil faster. Ideally, use a mesh bag or a basket in a dark pantry or cupboard. This method helps them last longer, ensuring you've always got some on hand for your cooking needs.
Can eating yellow onions improve health?
Absolutely! Yellow onions are packed with antioxidants and compounds that may support heart health, reduce inflammation, and even lower the risk of certain cancers. Incorporating them into your diet can be a tasty way to boost your overall health.
Why do yellow onions make us cry?
When you cut into them, they release a gas called syn-propanethial-S-oxide. This gas reacts with the moisture in your eyes, forming sulfuric acid, which irritates the eyes. To combat this, try chilling the onions before chopping to reduce the gas's effect.
Are yellow onions and sweet onions the same?
No, they're not the same. While both can be sweet, especially when cooked, sweet onions have a higher sugar content and a milder flavor. Yellow onions, on the other hand, have a more intense flavor and are more versatile in cooking.
How long do yellow onions last?
When stored properly, they can last for several weeks. If you notice any soft spots, mold, or an off smell, it's time to toss them out. For cut onions, wrap them tightly in plastic wrap or place them in a sealed container and refrigerate. Use within a few days for the best quality.
Can you freeze yellow onions?
Yes, you can freeze them, but it's best to chop or slice them first. Freezing alters their texture, making them softer once thawed. They're perfect for cooked dishes where the texture isn't the main focus. Just pop them in a freezer bag, and they'll be good for several months.
