The Science Behind the Perfect Raspberry Lemon Cake
Master these key techniques for success:
- Creaming Method: Beating butter and sugar until light and fluffy traps air, creating a tender crumb.
- Acid Balance: Lemon juice and zest enhance flavor while reacting with baking powder for a better rise.
- Berry Distribution: Tossing raspberries in flour prevents them from sinking to the bottom.
- Moisture Control: Sour cream or yogurt keeps the cake rich without being dense.
