No stove required: Whip up these simple, so-good sauces right in the blender. Tuck away that saucepan. Turn off the stove. When summertime heat (or mid-evening laziness) sets in, you don’t want one more thing on your to-do list. And you definitely don’t want to cook for hours in the kitchen. But you, being the divine foodie you are, also don’t want to leave dinner undone. Or un-yummy.
