Onions Q&A

An onion should be firm, have a “crunchy’ dry outer skin, have a mild smell. If the onion has a very strong smell it is most likely starting to go bad. Onion should be heavy for its size. Onions store better in a cooler and darker well ventilated area.

Do not cut off the hairy root end because it has the highest concentration of sulfur which causes you to cry. You can also chill the onion for 30 minutes prior to cutting to reduce the sulfur effect.

What if I only need to use part of my onion. Can I store the rest? For how long?

Yes, onions that are chopped or sliced can be kept for 7-10 days in a sealed container.

Fun fact from Fannie Farmer: She writes in The Boston Cooking-School Cook Book, “the onion belongs to the same family (Lily) as do shallot, garlic, leek, and chive.  Onions are cooked and served as a vegetable.  They are wholesome, and contain considerable nutrient, but are objectionable on account of the strong odor they impart to the breath, due to volatile substances absorbed by the blood, and by the blood carried to the lungs, where they are set free.”  Fannie teaches the reader how to boil onions, make onions in cream, as well as scallop, fry and stuff onions.
