Onions

The Wonderful World of Onions

Onions are the workhorse vegetable of the kitchen. We use onions in so many different ways- they add an underlying note of sweetness to dishes from Italian, Asian, French and of course American. But for many people preparing them to be used in a dish is the less than desirable part as their fragrance can be tear-inducing; my mother-in-law keeps a pair of swimming goggles handy for just such moments! For some people getting this unpleasant task done in one fell swoop is also a big-time saver. You can chop several pounds worth of onions and put them into small serving size zip lock bags, remove as much air as possible and freeze. For longer storage and to prevent freezer burn place these small bags into a larger 4 mil freezer bag and seal tightly.

Another way to keep onions handy is to dehydrate them. One word of warning - you may want to move your dehydrator outside as their fragrance will be quite intense. You can slice them into ¼” rings, place on dehydrators trays at 130° for 6-8 hours. Alternatively, you can also chop them into ¼ - ½ inch pieces and dry for 6-8 hours (The Dehydrator Bible, 2009). They should be dried to the brittle stage. Then place in the freezer for two days to pasteurize before packaging. The heat from a dehydrator is not high enough to kill bug eggs. Freezing the dried produce for 48 hours kills any bug eggs that may be on the product. At this point, they can be placed in airtight containers, and stored in the pantry for up to one year safely.

Now for those of you feeling a bit more adventurous, I have a fantastic recipe that is perfect for end-of-summer barbeques. It will go great on a burger or sandwich but would be a perfect topping for pork chops as well!

Combine onions, sugar, and vinegar in a stainless-steel pot. Stirring often, cook over medium heat until liquid evaporates (13 minutes).

Place peppercorns and bay leaves on a 5-inch square of cheesecloth; tie with kitchen string, and add to onion mixture.

 

Add apple juice and raisins; stir in pectin. Bring to a rolling boil that cannot be stirred down over high heat, stirring constantly.

Hold spice bag to one side of pot with tongs. Add sugar, stirring until dissolved. Release spice bag. Return mixture to a full rolling boil. Boil hard for 1 minute, stirring constantly. Remove from heat; remove and discard spice bag. Skim foam, if necessary.

Ladle hot marmalade into hot jars, leaving ¼-inch headspace. Remove air bubbles. Wipe rims with a dampened clean paper towel; adjust two-piece metal canning lids. Tighten ring to finger-tight.

Process in a boiling water or atmospheric steam canner for 15 minutes at 0-1,000 feet elevation, 20 minutes at 1001-3,000 feet, 25 minutes at 3,001-6,000 feet, 30 minutes at 6,001-8,000 feet, and 35 minutes at 8001-10,000 feet.
