For realz! Ice cream made in a pan in the freezer! I couldn't believe how nicely this came out. It *looks* a little funky, but let it soften and scoop it out, and it's amazing.
Here's the recipe. I won't rehash, but will just mention that (1) I forgot the straining step, which didn't cause any catastrophes (except maybe the aforementioned unpromising visual aspect), (2) I don't have a kitchen scale to measure everything superprecisely and this still came out fine.
Regarding pectin: If you buy Pomona Universal Pectin (they have it at Whole Foods, in the aisle with the spices), the box will contain 2 little packets. One of them is calcium - you don't need it here; the milk provides that. The other has the pectin mix, and that's what you use. Again, I have no kitchen scale, and I decided somewhat arbitrarily (math skills failing me in the heat of the moment) that 1.6 grams would be about 5/16ths of a teaspoon - that is, 2 1/8 teaspoons-ful, and then another half-filled 1/8 tsp. It worked.
Nor do I have an immersion blender, but pouring the wet stuff into a glass bowl and using a hand mixer to add the dry stuff worked fine and seemed easier than getting my blender dirty.
I added cinnamon to the ice cream, too, and served with (1) some tasty store-bought caramel sauce and (2) poached pears. Serious yumminess.
