For best flavor, use fully ripe, sweet strawberries and fresh lemons, and make sure all refrigerated ingredients are at room temperature so the batter emulsifies properly and the cupcakes bake evenly. Avoid overmixing once the flour is added to keep the crumb tender, and if your strawberries are very juicy, pat them dry to prevent dense spots in the cupcakes. You can make the strawberry filling and buttercream a day ahead and refrigerate them, then bring them back to room temperature and rebeat the frosting before piping. Adjust the sweetness and tartness of the buttercream by adding more powdered sugar for a thicker, sweeter frosting or more lemon juice for extra tang, and garnish with thin strawberry slices or lemon zest just before serving for a fresh, pretty finish.
