Well... key lime in spirit anyway. I used plain old regular limes. Um, except they were big and yellow and looked like lemons, so the ice cream didn't turn out green at all. Nonetheless, this is the limiest! And did I mention easy? No cooking! Mix the stuff in a bowl, and into the freezer in minutes flat. No excuses now!
Key Lime Pie Ice Cream
1 1/2 cups whole milk
1/2 cup heavy cream
1 (14-ounce) can sweetened condensed milk
1/2 cup lime juice (or juice from 2 big limes, whichever is more), or bottled Key lime juice
Zest from 2 big limes
Dash of salt
8 graham crackers (2 cookie sheets), coarsely crushed
In a large bowl, combine milk, cream, sweetened condensed milk, lime zest, lime juice, and salt; whisk to combine.
Pour mixture into your ice cream freezer, and freeze according to manufacturer's instructions. Stir crushed graham crackers into ice cream. Spoon ice cream into a freezer-safe container, cover, and freeze until firm. Serve with extra crumbled graham crackers, if desired.
