FAQ
Frequently asked questions.
How long do white onions last?
Whole white onions can last 2 to 3 months when stored in a cool, dry, and dark place with good ventilation.
Can you freeze white onions?
Yes, you can freeze chopped white onions. They will lose their crunch, so they are best used in cooked dishes after thawing.
What is the difference between white and yellow onions?
White onions have a sharper, cleaner flavor and thinner skin. They are crunchier and often used raw in salsas, whereas yellow onions are sweeter when cooked.
How do I pick a good white onion?
Look for onions that feel heavy for their size, are firm to the touch, and have dry, papery skin with no visible sprouts or soft spots.
What can I substitute for white onions?
Yellow onions are the best all-purpose substitute. For raw applications, shallots or red onions can be used, though the flavor profile will change slightly.
Why do white onions make you cry?
When cut, onions release a gas called syn-propanethial-S-oxide, which reacts with the moisture in your eyes to form a mild sulfuric acid.
Are white onions keto-friendly?
In moderation, yes. They contain about 9g of carbs per 100g, so they should be factored into daily carb limits.
How should I prep white onions for salsa?
Finely dice them and rinse under cold water to remove the excess sulfurous compounds, ensuring a crisp texture and clean taste.
Are white onions considered a root vegetable?
Yes, they are bulbs that grow underground, making them a root vegetable and generally avoided in Jain or strict Sattvic diets.
