FAQs

1. Can I make the Crispy Rubies ahead of time?

Yes! They're best served fresh, but you can make them a day ahead and store them in an airtight container at room temperature. They might soften slightly but will still be delicious.

2. What if my Crispy Rubies don't turn golden brown?

This usually means your oil isn't hot enough. Make sure the oil reaches the correct temperature (around 350°F/175°C) before adding the rubies. Also, ensure they aren't overcrowded in the pan.

3. Can I substitute ingredients?

Some substitutions are possible. You can experiment with different types of flour (though rice flour is traditional), but the tapioca starch is crucial for the texture. Coconut milk is also key for flavor and texture.


With their delightful combination of textures and flavors, these Crispy Rubies are sure to become a new favorite dessert.
