Cantaloupe and honeydew are mild in flavor, and mix well with yogurt. If your melons aren't ripe enough to mash easily, purée in the food processor before blending with yogurt.
1 slice honeydew or cantaloupe
3 tablespoons whole-fat yogurt
Cut a thin slice of a ripe melon, and remove all seeds. Slice the fruit off of the rind and fork-mash on a plate.
Blend in the yogurt with a spoon. Mix thoroughly.
Most babies will not consume an entire honeydew at a week's worth of sittings, much less a single meal. For the grownups, try slicing up the leftovers and serving with a thin piece of prosciutto on top. Children like the fun shape of melon balls — use a melon-ball tool or, if your children are big eaters, an ice-cream scoop!
