Frequently Asked Questions
Can I use other types of flour instead of potato flour?
Yes, while potato flour provides a unique texture, you can substitute it with cornstarch or all-purpose flour. However, the sponge cake may not be as light and airy. If using all-purpose flour, you may also want to sift it to aerate further.
How can I tell when the cake is done baking?
The cake is done when it's golden brown and springs back when lightly pressed in the center. You can also insert a toothpick into the center; if it comes out clean or with a few crumbs, the cake is ready.
Can I add flavors or other ingredients to the batter?
Absolutely! You can add flavorings like vanilla or almond extract to enhance the taste. Additionally, folding in some lemon zest or a handful of berries can add a lovely twist to the sponge cake, making it even more delightful.
