FAQ – Frequently Asked Questions

Can I use corn starch instead of potato starch?

You could use corn starch, but the glaze will not be clear but instead cloudy. Tapioca starch is an alternative for potato starch and will result in a clear glaze.


Try different fruit juices to enhance the flavor and color or your glaze.

Use white grape or apple juice for yellow colored fruit toppings. Red juices will enhance the color of strawberry and raspberry cakes.

For an even more intense flavor you can mix 1 or 2 tbsp. of syrup with the water or juice.
