Remember back in the summer, when I said I was saving vegetable scraps in the freezer to make vegetable stock? I finally got around to doing just that.
It was really easy. First, I put a little olive oil in the bottom of my stock pot. I heated that on medium, and added all my onion and garlic type scraps (leeks, onion pieces, garlic scapes). I stirred that until it was soft (about 10 minutes), then I added some of my tougher or more fragrant scraps, such as carrots, celery and parsnips. I let that cook for another 10 minutes, then just covered everything with water. I let it come to a boil, them tossed in some of my softer scraps, like salad scraps (lettuce, radishes, tomatoes). I added just enough water to cover, and let the whole pot simmer for about 45 minutes. Then I turned off the burner and let it cool.
Once it was cool, I ladled it into appropriately-sized freezer containers, straining it through a fine wire mesh as I poured. I got about 5 1.5-cup containers worth of stock. I froze three of them and used two within the next few days, and they’ve worked great for everything from soup to risotto. For things like risotto, I let the stock thaw in the fridge for 8-24 hours before using, but when making soup, I just tossed in the giant ice cube.
