Can you substitute another starch for the corn starch?

Thanks! I actually have Arrowroot on hand. Also have potato starch as well. I haven't done much GF baking yet except for a few mixes that weren't all that great. Thanks again!

I always use potato starch in lieu of cornstarch.

I agree Flesch! Arrowroot is awesome, I used it in placeof three tbs. of cornstarch in an ice cream base recipe and it was really good!

Potato starch would work well.

You could try arrowroot, which turns out very similar to cornstarch. The only difference is arrowroot is more expensive

I've tried subbing rice flour for cornstarch.. it worked, but definitely not the same texture. In the recipe you posted it seems like such a small amount of CS that you might be able to get away with it.
