I came up with this strawberry rhubarb cake when I wanted to make something with rhubarb and strawberries that wasn't a pie. If you know someone who hasn't tried rhubarb before, this is a great way to introduce them to it. —Theresa Kreyche, Tustin, California

buttermilk

To substitute for each cup of buttermilk, use 1 Tbsp. white vinegar or lemon juice plus enough milk to measure 1 cup. Stir, then let stand 5 min. Or, use 1 cup plain yogurt or 1-3/4 teaspoon cream of tartar plus 1 cup milk.

Rhubarb

If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out.
