FAQs
1. Can I make Banh Troi ahead of time?
It's best to make Banh Troi fresh, as the texture can become slightly less chewy if stored for too long. However, you can prepare the dough and filling in advance and assemble and cook them just before serving.
2. What if I don't have all the traditional fillings? Can I substitute?
Absolutely! Feel free to experiment with different fillings like sweetened mung bean paste, chocolate, or even sweet potato. The key is to ensure the filling is not too wet to prevent the Banh Troi from breaking apart.
Making Banh Troi is a rewarding experience, connecting you to Vietnamese culinary traditions and allowing for creative expression with fillings and colors.
