1) Store onions in tights (a little extreme we admit)
Tie a knot between every onion with a pair of nylon stockings. By doing so, the onions will last up to 8 months, because they’re in fresh air and not squashed against each other.
2) Don’t store in plastic bags: Because of the lack of air circulation you will find them rotting, spoiling, sprouting much sooner.
3) Keep potatoes away from onions: They give off gases that will accelerate spoilage of each other.
4) Dark / Cool (but not cold) storage area is best. Storing in the fridge will soften the texture + onions will give off scents into other food.
5) Store onions in paper bags that have holes in them. If you can’t buy the bags then grab a ton of paper bags and then use an office hole punch or better still a belt hole maker.
6) Select the good looking onions when you’re actually buying them + pay decent prices for them. Compare prices between pre-packaged and
