Great Substitute
Prepare as directed, except substitute chocolate frozen yogurt for chocolate ice cream.
Storage Know-How
Since ice cream tends to form ice crystals and absorb the odors of other foods in the freezer, it is best to use the ice cream within 2 to 3 days after purchase. When freezing for longer periods of time, double wrap the ice cream container in a freezer-weight plastic bag and freeze up to 2 months.
