For best results, use room-temperature eggs. This helps the batter emulsify properly in the blender. If you don't have self-rising flour, you can make your own by combining 2 1/4 cups all-purpose flour with 3 1/4 teaspoons baking powder and 1/2 teaspoon salt. The maceration time for the strawberries can be adjusted to your preference. The longer they sit, the more juice they will release. Feel free to add a splash of orange liqueur to the macerated strawberries for an extra layer of flavor.
