Place plums in a vegetable steamer. Steam, covered, 7 minutes or until very tender.
Place plums in a food processor; process until smooth.
Kitchen Tip The riper the fruit, the less steaming time it takes to soften the flesh, so use the lower end of the cook time range.
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).
