Canniing 101: Sweet Onion Relish....AKA Rosemary Onion Confit

I've spent the winter and spring looking at all kinds of canning, pickling, and preserving cookbooks, posts on Pinterest, and various canning websites looking for new recipes to try out. I've pretty much got the basics down of what we like to eat, but sometimes it gets boring and predictable. I like to cook, and I love trying new recipes for just about anything. When Kevin told me the onions in the garden just weren't going to keep as we'd like (too much water all spring), while he started pulling the onions, I went in search of a recipe to use onions in.

I came across Pickles & Relishes:  From Apples to Zucchini by Andrea Chapman on my Scribd subscription. If you don't subscribe to Scribd, you can find her book here on Amazon  I've found quite a few recipes in her book that I want to try out, especially the 1-jar pickle recipes, just in case a recipe turns out to be one we don't care for, but after trying this Rosemary Onion Confit, I have a feeling all the recipes in her book are going to be great.

I did make a few modifications to her recipe, as I usually do, but I did not change the vinegar amount. That is what will be preserving the onions, so I didn't mess with it. I wasn't sure as it was cooking if it would be something my family would like or not, but once everything pulled together and I was ladling it into jars, I took a taste, and man was it good! Here's the recipe, with my modifications:

Sweet Onion Relish

1/4 cup extra-virgin olive oil
3 pounds onions, chopped
1 cup cider vinegar, or wine vinegar (I used apple cider vinegar...5% acidity)
3/4 cup sugar
1 large sprig fresh rosemary
1/2 tablespoon soy sauce (Andrea's recipe called for 1 tablespoon or to taste)
Freshly ground black pepper (a few turns on the grinder...to taste)

Heat the olive oil in a large saucepan over medium-high heat. Add the onions. Decrease the heat to low and stir to coat the onions with the oil. Cook, stirring occasionally, until the onions are translucent and soft, about 30 minutes.

Stir in the cider vinegar, sugar, rosemary, soy sauce, and pepper. Simmer for another 5 minutes.

Pack the onion mixture into clean, hot half-pint jars, leaving 1/2-inch headspace. Remove any air bubbles and seal.

Process in a boiling water bath for 10 minutes.

Let the jars stand undisturbed for 12 hours. Do not open for at least 6 weeks to allow the flavors to develop.

Yield:  Approximately 4 half-pints

Note:  I tasted the relish after I ladled it into the jars, and what was left in the bottom of the pan was awesome. I can't wait for 6 weeks to pass so I can have some with a grilled steak!
