My grandmother and aunts made this for family gatherings to go along with fresh homemade ice cream. I now share it with my family and friends during special gatherings. —Keith Gable, Goddard, Kansas

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.
