FOOD ADVENTURES OF A COMFORT COOK


“Memories of the meals we’ve made before. Misty, watering, burning eyes. While dicing onions from the store.”

If Barbra Streisand sees what I’ve done with her “The Way We Were” song lyrics, I am a dead woman.

Whether a home cook or restaurant prep cook, we all know the pain of dicing and slicing onions.

As a sharp knife begins the cutting process, the friction warms the onion, releasing its juice and sulfurous fumes. Even though the fumes can be stemmed for a very short time by getting onions cold in the refrigerator, as they warm up, they fight back with a skunk’s vengeance.

Alright kids, time for a little geeky science: Onions (Allium cepa) contain Amino acid sulfoxides that form sulfenic acids when the onion is cut into.

These isolated enzymes are now free to mix with sulfenic acids to produce Syn-propanethial-S-oxide, a volatile sulfur compound gas. This gas reacts with the water in your tears to form sulfuric acid, and there’s the burn.

Now for some nutritional facts to round out our education on the onion: 3.5 ounces of raw onion is 40 calories; has 1.7 grams of fiber; and contains Vitamins B6, B9, C, and the mineral potassium. They are beneficial in blood sugar and pressure control, immunity boosting, cell growth and metabolism.

The benefits far outweigh a bit of temporary irritation to the eyes.

All onions are definitely not the same. While yellow are strong flavored, white are milder and clear in color. Purple and Vidalia do not release strong fumes like the yellow variety and are milder in flavor as well.

Shallots (eshallot) are a French variety mainly used in sauces or salad dressings. As with garlic, they can be roasted to a candy-like sweetness.

Leeks are long onions with a good portion of the body growing underground. They are perfect for soups or as a side dish.

When I taught Adult-Ed cooking classes back East, I learned quickly that many students are clueless on onion cutting techniques. I could write it all out here, but this is one of those cooking lessons that is best done visually.

Can’t do that in a written article though, so I’ve included photos of the lesson sheets I handed out to my class at sjrnews.com.

While my diagrams are crudely drawn, they do the job of teaching and that is what matters most.

This is a “Hey, this is how we made drawings before computers and Photoshop!” moment.

So class, I’m going to give two homework assignments. The first is how to caramelize onions. The second is how to create Sweet Onion Relish. There will be a taste test, and I expect you all to pass with deliciously flying colors!

By the way, I would like to dedicate this article to Rick Meyer of Blanding, the San Juan County Health Inspector and loving husband to Jonna Lancaster Meyer. And he knows why. *wink*

Caramelized onions

Caramelizing onions is simply giving long (one hour) cooked onions a deep brown color and bringing out the sweetness of the onion itself. Using medium and low heat temperatures ensures the onions will attain a brown coloring from the caramelizing of their natural sugar.

Higher heat temperatures will brown the onions, perhaps even burn them. However they may remain bitter from not releasing and utilizing the sugar.

They can be used as an added ingredient (for example: quiche, frittata, macaroni and cheese) or accompany meat, pork, poultry, or seafood, and are the main ingredient in French Onion Soup.

There is no one particular type of onion that should be used when caramelizing. White, yellow, red, even sweeter onions such as Vidalia and Spanish work just fine.

Remember, we’re letting the natural sugar of the onion do most of our work for us, so the sweeter the onion, the richer the caramelizing will be.

Also, while I prefer simply to use olive oil for the initial cooking process, some like butter, or a combination of oil and butter.

I don’t personally like to add a dairy product into my caramelizing process. I don’t believe it truly adds anything but a greasy texture to it.

I’ve seen some recipes add brown sugar. I’m not sure why since brown sugar is caramelized sugar, and that’s what we’re trying to achieve with the onion’s own sugar. Confusing, isn’t it?

I do, however, add a little balsamic vinegar for extra richness. It enhances the aroma of the onions. Play around with the techniques and see what suits your tastes the best.

Caramelized Onions

Ingredients:

3 Tbsp. olive oil; 5 large onions, peeled and julienned; ½ tsp salt; 2 Tbsp. balsamic vinegar

Preparation:

Slice the top and root off the onions. Cut the onions in half from top to bottom; remove peels and discard.

Place half of an onion, flat side down, on a clean, flat cutting surface. Angle the knife towards the center to make ¼ inch slices from stem to root end.

This method of slicing onions is called “Frenched onions,” French-cut, or Julienned.

Heat oil on medium heat in a large skillet; spread onions in skillet and sprinkle salt over them.

Cook the onions until soft and translucent (10 minutes), stirring occasionally. Reduce heat to low; cover and let cook for 40 minutes. Stir after 20 minutes only. This will make the onions sweat, drawing out the natural sugars that will coat the onion pieces and cause them to turn brown as the sugar itself begins to cook.

Do not keep removing the lid to check on the onions, or stir them; the heat will lower and you’ll lose the accumulated moisture. After 40 minutes, mix in the vinegar, cover, and cook additional 10 minutes.

Makes 2 cups.

Note: if you want the onions to be darker colored than what is in my accompanying photo, let them cook down longer on the low heat. For us, after one hour, the intoxicating scent throughout the home is just too much to bear, so we gobble them up.

How to make

Sweet Onion Relish

Types of sweet onion which have a mild sulfuric, and higher water, content than regular onions are Vidalia from Georgia, Walla Walla from Washington state, Sunbero from Nevada, and Maui from the Hawaiian island of Maui; to name a few.

Red onions, also called purple onions, are also mild and sweet; their coloring brightens up any dish.

One way to use sweet onions is to make a relish which can be spread on toasted bread, used as a condiment on sandwiches, or an enhancement for beef, pork, or poultry.

Sweet Onion Relish

Ingredients:

2 Tbsp. canola oil; 6 cups chopped sweet onions; ½ cup chopped celery; ½ cup sugar; ¼ tsp. salt; ½ tsp. celery seeds; 1/8 tsp. ground black pepper; ½ cup cider vinegar; ¼ cup water; ¼ cup diced roasted red peppers

Preparation:

In a large skillet, heat oil on medium heat. Add onions and celery; sauté until tender.

Mix in remaining ingredients; bring to a boil.

Reduce heat to low and simmer uncovered for 30 minutes, stirring often. Let cool. Spoon into a bowl; cover and chill for eight hours.

Makes 4 cups.

Have fun on the onion journey and don’t be ashamed to shed a few tears of joy.
