Easy Freezing This recipe is based on 1/4-cup serving sizes. If you freeze batches in ice-cube trays, one cube usually holds 2 tablespoons. We recommend defrosting just one cube when baby is new to solid food. Later on when baby has started eating more, defrost two to four cubes (2 to 4 ounces or 1/4 to 1/2 cup).
