1. Preheat oven to 400°.
2. Leave root and 1-inch stem on beets; scrub with a brush. Wrap each beet in foil. Bake at 400° for 1 hour or until tender. Remove from oven; cool slightly. Trim off beet root; rub off skin. Cut beets in half. Place in a food processor; process until smooth, adding water, 1 tablespoon at a time, if needed, 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).
