FAQs
1. Can I substitute the sugar in the recipe?
While granulated sugar is recommended for its optimal texture, you can experiment with caster sugar. Avoid using brown sugar as it will alter the cake's color and lightness.
2. Why is my Bak Tong Gou dense instead of fluffy?
This usually happens due to overmixing the batter or baking at too high a temperature. Ensure you gently fold the ingredients and bake according to the recipe's temperature and time.
3. How can I store leftover Bak Tong Gou?
Store the cooled cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. Wrap it tightly to prevent it from drying out.
With its delicate texture and subtle sweetness, your homemade Bak Tong Gou is sure to be a delightful treat for everyone. This recipe proves that creating a beautiful and delicious Asian dessert can be surprisingly simple and rewarding. Enjoy the fluffy goodness!
