Honor your Mom this Mother's Day with strawberry-rhubarb shortcake. Strawberries and rhubarb are a classic pair and work deliciously in this shortcake recipe. Sliced rhubarb is cooked with orange peel and strawberry preserves until thick and syrupy. Once cooled, fresh strawberries are added to the mixture. The fruit is tucked in the center of a buttery homemade biscuit with freshly whipped cream. Any Mom would be thankful to dine on this delightful dessert on their special day.
