Pierce each potato several times with a fork. Bake at 400° for 55 minutes to 1 hour or until tender. Cool 45 minutes or until cool enough to handle.
Peel sweet potatoes. Place flesh in a food processor; process until smooth, adding 2 tablespoons water, formula, or breast milk, 1 tablespoon at a time, to reach desired consistency.
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).
