How to make Taiwanese castella cake: with these tips and tricks you will succeed
- The proportions are the most important thing in this recipe. You must not change the proportions in any case.
- Use exactly the baking pan indicated in the recipe. I baked the Taiwanese castella cake in a round, Ø 18 cm springform pan. So the quantities in the recipe fit only for this baking pan. If you want to use another pan, you have to convert the ingredient amounts.
- Depending on the size of the baking pan, the baking time may vary.
- Prepare the baking pan and all ingredients before you start baking, i.e. weigh everything first, sift flour, separate egg yolks from whites.
- Sift the flour to avoid lumps in the dough.
- Eggs for the cake must be at room temperature.
- Add egg yolks to the flour-milk-butter mixture only after it has cooled to warm. You must not add them to the mixture while it is still hot.
- Add the entire amount of sugar to the egg whites at once and then whip it.
- The egg white-sugar mixture should be airy and not stiff after whipping.
- You should carefully stir the egg yolk-flour-milk-butter mixture into the egg white mixture so that the batter ends up with an airy consistency.
- Vanilla ensures that the cake does not smell like eggs.
- Covering the baking pan with aluminum foil ensures that no water gets into the batter during baking, since the cake is baked in a water bath.
- The water in which the cake is baked must be 80°C when you pour it around the baking pan with the batter. It must not be hotter than that, and it must not be cold.
- Do not fill the ovenproof dish in which the springform pan with the dough is placed too full with water, so that the water does not spill over the edge of the springform pan into the dough during baking.
- It is best to use a kitchen thermometer to maintain the temperatures specified in the recipe.
- Do not open the oven door while the cake is baking.
- The Taiwanese castella cake is done baking when it has a light brown surface and is a little wobbly.
