How can I make my Ice Cream "creamier"? My ice cream doesn't feel creamy enough. I got the recipe from Good Eats, and I can't tell if it's just the recipe or that I'm just not getting my "batter" cold enough before I try to make it. I let it chill overnight in the refrigerator, but it doesn't always come out of the machine looking like "soft serve" as he said on the show - it's usually a little thinner.

More fat!

Your recipe has two dairy components (half and half and whipping cream). The half and half is half cream, half milk. To increase the fat, experiment with using more cream and less half and half.
