My grandma used to make this simple, moist, nostalgia-inducing castella cake. This recipe only call for 4 ingredients and doesn't require a scale. It's super easy.
This is the recipe from my grandma, who loves castella and used to make this for me. This is just the right size as a gift.
Whipping the egg whites really well makes the castella fluffy.
