Instructions
- Heat the steamer pan. Wrap the pot lid with a cloth.
- Prepare a bowl and add flour, granulated sugar, eggs, SP, vanilla and half a measure of soda water, then beat with a mixer.
- While shaking, add the remaining soda water little by little, until the soda water is gone. Beat until fluffy, thick and white.
- Divide into 5 equal parts, then add 3-5 drops of coloring to each part. Stir well.
- Pour the mixture into a sponge mold that has been lined with a paper cup. Pour each one spoonful alternately until full.
- Steam for 10 minutes over medium heat.
- Lift and serve.
- 1. To be able to steam a lot at the same time, use the Supra 3 Stack Steam Pan (See Lazada DISCOUNT) with a diameter of 24 cm. Because it is a stacked steaming pan, this SUPRA Steaming Pan is made from quality stainless steel. So, you don't need to worry because the cake will definitely cook evenly. 2. When steaming, use medium heat, tend to be high so that the sponge cake can bloom perfectly. 3. Soda water functions like baking soda, namely so that steamed cakes can bloom perfectly (failure-proof).
