When I tell my friends that I spent my weekend making ice cream (which has so far happened five times this summer), they usually comment with something like, "Oh, that sounds cool. I'd like to do that, but I don't have an ice cream machine."
Well...that's no excuse. David Lebovitz's post about making ice cream without a machine should instill confidence in those who want to make ice cream but who only have a bowl and spatula on hand. The manual method takes more attention, labor, and time (2 to 3 hours) than just popping the ice cream base into a machine, but as dddg commented on David's post, at least you'll burn some calories before digging into a bowl of sweet, fatty, dairy-filled goodness.
And if you still feel like you need a machine, this conversation in Talk might appeal to you: The best at-home ice creammaker?
