Featuring a classic buttery shortbread base and silky and sweet red grapefruit topping, the cheerful color palette and bright citrus flavors make these shortbread bars a refreshing treat for spring. Use freshly squeezed juice for best results, and don’t skip the lemon – it creates the perfect balance of tart and sweet. To make the topping more vibrant, add a few drops of red food coloring, or leave as is for a perfectly pretty pale pink.
