I made this a week or so ago to rave reviews. My eldest child says it should be illegal to make food this good.
Skill level: one step up from dead easy
Yield: 5-6 cups (I got 5 and a bit)
Ingredients: 4 pounds videlia or Spanish onions, about 8
3 heads garlic
some olive oil (I didn’t measure) or butter
1 tbsp kosher or pickling salt (don’t use table salt if you’re canning stuff)
4 tbsp balsamic vinegar – red wine or malt vinegar would work, too
1 tbsp (i.e. a dollop) fancy molasses
Follow instructions on the internet for roasting whole heads of garlic if you don’t already know how. Set them aside to cool. Meanwhile, chop the onions into half-inch strips; I used my food processor for this. Have I mentioned how much I love my food processor?
Cook the onions with the salt and some olive oil until they are nicely carmelized. You’ll achieve a darker colour if you use butter in this part of the recipe. I wanted it vegan so I didn’t and it tastes incredible, so you do you.
While the onions are cooking down – it’ll take an hour or more in a pretty big pot – squeeze the garlic pulp into a bowl and mash it with a fork. Don’t stir the onions too much; they don’t get brown as fast if you stir too much.
When the onions are almost done cooking, add the rest of the ingredients. You may want to test for sweetness at this point. I’ve been aiming for low-sugar-added recipes, but the recipe I used as a base for this one called for two tablespoons of brown sugar instead of molasses. Again, you do you.
If you’re an experienced canner, you started the boiling water canner while the onions were cooking down. I used jam jars, aka half-pint, aka 250mL. Take the jars out of it now, fill them, affix seals, and process for ten minutes. If you need more instructions on this, find a friend to do it with, but it’s exactly like jam at this point.
I’m expecting to use this on a wide variety of sandwiches and meat and cheese dishes. It’s a pretty thick stringy paste and would go great with some Brie and pear on a grilled sandwich. I’m also expecting to use it as a topping for a mashed sweet potato casserole, because sweet potato + carmelized onion + roasted garlic = heaven in an orange mush.
