Nutrition values are an estimate, per cube. Freeze time is about 4 hours, or until solid. Freeze completely before removing from the tray, then store in a freezer-safe bag or container for up to 2 months. Microwave: place 1 to 2 cubes in a bowl with 2 to 4 tbsp (30 to 60 ml) milk and heat for 30 to 60 seconds, stirring halfway. Stovetop: add 1/4 cup (60 ml) milk per 2 cubes and heat over low heat, stirring occasionally. Add more milk as needed. Most children enjoy 1 to 2 cubes; older kids and adults 2 to 4.
