Use a Steamer Basket to Store Onions and Garlic
If you have a bamboo steamer basket and there is little storage space in your kitchen, make the steamer basket double-duty by storing onions, garlic, and shallots in it. This is why it is perfect for the job.
Bamboo steamer baskets are designed to let in and out air (and steam), which is also an ideal medium for storing onions and garlic. They will stay protected and cool, keeping them fresh whenever you want to cook with them. You will have to peel the basket out of the skin before using the basket again for cooking, but to make the most of your storage space, it is worth taking a few extra seconds to clean up.
