Having just dissed the home-made curry powder, I am going to say totally the opposite about ice cream. Home-made is hard work, and takes a long time, but it is TOTALLY worth it.
This was a basic vanilla recipe, with coffee, strawberry and chocolate variants, so I made a double batch and divided it into four so I could do all four flavours. I'd be hard-pressed to tell you which one I liked most.
Not GI/dairy/anything friendly, really, though. My double batch involved 2 pints of milk, 2 pints of cream and a dozen egg yolks. You basically brew up a custard with the milk and eggs and some sugar. Don't let it boil, but stir it up. Throw it in a cooled container (or four in my case) after adding whatever flavour you're adding, and freeze for two hours. Stir in the cream (whipped) and freeze again for two hours. Take it out and mash it up a second time before freezing it again a final time.
It is REALLY good. Notably better than the average store bought stuff. The teen even admitted that the chocolate variant was the best he'd had all year. (!!)
