Pickled Red Onions

This bright, jewel-toned condiment offers a zesty tang to countless dishes and adds a lovely splash of colour as well. It takes about 10 minutes to assemble and lasts for weeks in the refrigerator. There are countless uses for pickled onions. Tuck them into sandwiches, especially those with rich meats, like pulled pork; use them as a condiment to top tacos, bean dishes, and rich mayo-based salads, like potato or egg salad; toss them into lettuce salads, grain salads, and salads with sturdy greens, like kale. Their bright-pink colour, crunchy texture, and piquant flavour will perk up almost any dish. They're also perfect for serving with sandwich and salad buffets at parties.

1 medium red onion (about 5 oz)
½ tsp. sugar
½ tsp. kosher salt
¾ cup rice vinegar, white vinegar, or apple cider vinegar

Flavourings (optional):
1 small clove garlic, halved
5 black peppercorns
5 allspice berries
3 small sprigs thyme
1 small dried chili

Slice the Onions:
Start 2 or 3 cups of water on to boil in a kettle. Peel and thinly slice the onion into approximately ¼" moons. Peel and cut the garlic clove in half.

Dissolve the Sugar and Salt:
In the container you will be using to store the onions, add the sugar, salt, vinegar, and flavourings. Stir to dissolve.

Par-Blanch the Onions:
Place the onions in the sieve or colander and place the sieve in the sink. Slowly pour the boiling water over the onions and let them drain.

Store:
Add the onions to the jar and stir gently to evenly distribute the flavourings. The onions will be ready in about 30 minutes, but are better after a few hours. Store in the refrigerator. They will keep for several weeks, but are best in the first week.

Makes about 2 cups.

Cook's Notes:

The Onions:
I like to cut my onions into rings because I find the tangled loops are easier to scoop from the jar and I like the way they look. If you prefer, you can also cut the onions into half moons. They can be sliced paper thin or into rather thick, ½" slices, but I like to split the difference and slice them slightly thinner than ¼" thick.

I only use red onions for my picked onions, but yellow or white onions can be used as well. Of course you won't get that lovely bright pink colour, but if that's not a factor, then give it a try. Be sure to use a firm onion that is free of soft spots and blemishes.

The Vinegar:
I usually use a pale coloured vinegar, such as rice vinegar or white wine vinegar. If I happen to be out, apple cider vinegar will do. Do not use the industrial white vinegar that comes in large gallon containers, as it is too harsh-tasting.

The Sugar:
The sugar provides a nice balance to the salty vinegar brine, but you can leave it out if you are avoiding sugar. Honey or another sugar substitute might work, but start with less just to be safe.

The Flavourings:
At their most basic, pickled red onions are simply sliced onions that have been covered in a mixture of vinegar, salt, and sugar, and allowed to marinate. It's a lot of fun to add additional spices and to customize the mixture to match your dish. In this recipe, I used my favourite mixture of flavourings, which includes fresh garlic and a chili for added oomph. You can leave them out or add additional selections, such as a bay leaf; herbs, like rosemary or oregano; orange peel; or cloves. Asian spices, such as star anise, cinnamon, Szechuan pepper, and fresh ginger, would also be a nice garnish for a rice-based stir-fry or other Asian dish.

Storage:
Over time, the onions will eventually turn a uniform shade of vivid pink. Be sure to store your pickled onions in a glass or ceramic container. Most metals will react with the vinegar, and plastic will absorb the flavours. I like to use a pretty canning jar so I can just grab the onions from the refrigerator and plunk them on the table with no fuss.
