Kitchen Techniques: Ingredients: Onions


Onions are one of my favorite ingredients. I use them in nearly everything. I enjoy them both raw and cooked.
Recipe Note: When I say onion, I am generally referring to the common yellow storage onion. There are many other onions in the world that are available at your well supplied grocery store like Green onions – scallions, Sweet onions, Leeks, Shallots, Ramps, Red Onions, White Onions, and Pearl Onions. I use these in recipes but I will always specify which variety when I am not using standard yellow storage onions.

Why use them? They provide a flavor punch with very few calories. In about ½ a cup of chopped onion (3.5 ounces) you only have 38 calories. They also provide 10% of the Vitamin C and Folacin you need.

Shopping for Onions: Onions should be heavy for their size. This means if you have two onions that are about the same size the one that feels heavier is the better onion. The difference in weight is due to water content. The outer skins should be papery. You can select your onions individually or you can just go ahead and buy the orange mesh bag of them (that's what I do). The mesh bag offers a fast way to get a bunch of onions.

Availability of Onions (Seasonality): Onions are available year round but are most common March to September when they are fresh to most markets. Onions store well given the right conditions so stocking up on them when you have a good price at market is not a bad idea.

Storage of Onions: Onions can last several months in ideal conditions and can go bad in a couple of weeks in crappy conditions. What, pray tell, are ideal and crappy conditions you may ask? Onions want a cool dry place with lots of circulating air. If it is too humid you will get sprouting onions or rotting onions. The mesh bag is ok for storage if you are going to eat up the onions in about a month (I go through a mesh bag every other week if I'm cooking 2 times a week), or if you hang the bag so it is exposed to a lot of air. If you are going to hold on to your onions for longer you might want to try to store them in pantyhose hung from the ceiling. (To store them in pantyhose place them - one at a time - into a clean pair of hose and tie a not between each so that they have their own little nylon sack.) As you need them you can cut off the onion(s) you need and leave the rest hanging. (This is a great use of nylons with runs. You can also use this with thigh-highs too.) Do Not store them in the fridge!! Storing them in the fridge causes them to rot – The exception to this is an onion that has been cut but not used entirely. If you have a half-used onion you can store it for about a week in the fridge before it will go bad.

Preparing Onions: Onions can present somewhat of a problem for cooks in that they are round and not easily chopped into regular pieces. Be sure you have a sharp knife. A dull knife is more dangerous than a sharp one as they tend to slip off what you are cutting and cut you instead. Also onions can make people cry so the faster you can get them cut the better off you are likely to be. Here is the technique I use to more easily deal with onions:
Cut off the stem end first, leaving the root end intact. Discard the stem end into the scrap bowl.
Then you peel off the papery outer layers and the first thin inner layer and discard into the scrap bowl. Then you turn the onion onto the cut stem end and slice off one side of the onion the thickness of the chop you are looking for.
Then turn the onion onto the freshly cut side and again slice off an un-cut edge at the same thickness.
Now make parallel cuts across the width of the onion making sure not to slice through the root end.
Now turn the onion over onto the second of the side cuts and make cuts parallel to it making certain not to slice through the root end.
Now you cut across the length of the onion getting the exact size pieces you want. Discard the root end into the scrap bowl. Chop the two remaining side pieces and move all the cut onion into a prep bowl.

Hints and Tips for Onions: Onions can make your hands smell funny after you've been handling them – try rinsing your hands with lemon juice to rid yourself of the smelly fingers (also works for garlic-fingers). Onions can make you cry – lots of old wives tales for solving this (and just like cures for hiccups) some work for some people others don't. Try a few until you find one that works for you (Light a candle next to your cutting board, hold matches in your mouth – heads out- to block the smell, put bread under your tongue, etc) Raw yellow onions are bitter – after cutting them, soak them in ice water. Change the water several times over the course of up to 2 hours before serving they will be oniony with out being bitter. Onion Breath? - Chew fennel seeds, Parsley leaves, gargle vinegar, or drink some coffee.

History: Onions have a long and distinguished career as a domesticated food-stuff. There is evidence from the Bible and other sources both literary and archaeological that the onion has been cultivated since about 3000 BCE. It is believed that onions were part of the diet of the slaves who built the pyramids.

Myths and Legends: It is said in early cultures that onions were linked to the afterlife or eternal life because of the concentric circles you see when you slice an onion across its middle. Onions are also believed to have medicinal qualities. I don't know if I believe that they can cure any diseases but I eat them and enjoy a decent level of health. (Then again my sister won't touch them and she is as healthy, and perhaps more healthy than I am)

Food Journal-
Breakfast – 2 doughnuts – Red Bull
Lunch – Lasagna (my own) and a bowl of wild mushroom and rice soup (also my own) – Mellow Yellow
Dinner – Spicy shrimp over rice noodles (my own) – Mellow yellow
Exercise? - Sort of, I walked home instead of hitting the gym.
