Abstract

A two-compartment package is provided which includes in a first lower compartment, frozen or refrigerated ice cream; and in a second upper compartment, frozen or refrigerated syrup with the frozen or refrigerated syrup being supported on a microwave reflective material and the microwave reflective material protecting the frozen or refrigerated ice cream from microwave energy whereby the rate at which the frozen ice cream located in the first lower compartment absorbs heat is much less than the rate at which the syrup in the second upper compartment absorbs heat. The first and second compartments are enclosed in a sealed container, the top surface of the second compartment of which is transparent to microwave energy. The second upper compartment may be an integral part of the food package or it may be a separate container means that is removably and tightly fitted within the upper portion of the first lower compartment.
