I freeze more than can. It's easier and doesn't make the house so hot. Even if I roast tomatoes before freezing, having the oven on doesn't compare to boiling water baths. Ugh. Love freezer jams, they taste so much fresher, although they are a softer set. There are only 2 of us here now, so I don't bake as much. I, too, make sourdough breads. I took a class in 2019 or so, didn't keep up with it, but started again when I stumbled upon an online teacher that made things more understandable. I thought I didn't like sourdough, but now realize I don't like packaged sourdough that has enhancers in it. When I bake it, I usually do enough for a month and freeze it. It doesn't take much longer than making one loaf, and then it's done for awhile.
