Easy Ice Cream in a Bag

Combine milk half-and-half sugar and vanilla extract in a pint-size resealable plastic bag; seal tightly.

Put a scoop of ice 3 tablespoons ice cream rock salt and the bag containing the milk-cream mixture into a gallon-size resealable plastic bag; seal tightly.

Rock the bag back and forth (do not shake) until contents thicken into ice cream about 10 minutes. Wipe salt from the top of the pint-size bag before opening to prevent salt from getting into the ice cream.
