Living here in Hawaii, aren't you envious to find that onions keep for months on end in a Midwest cellar? Here's are three ideas on how you can preserve your round onions in our humid paradise without waste.
1. Simply wrap each one in newspaper and store it in your refrigerator. It's as good as a cellar. The onion won't sprout and keeps for at least 3 months or more. Trust me, this one works.
2. Onions don't do well in the freezer as the water content causes it to become soft and mushy. However, if you grill them beforehand, you can freeze them in portion-sized clumps and they're very convenient for burgers, vegetables or whatever you would normally use grilled onions for.
3. Make a duxelles out of them and freeze. In addition to preserving your onion, it preserves your mushroom too. It's great for stews, shoyu chicken and anywhere you need a flavorful broth.
