You should substitute potato starch for cornstarch in a 1:1 ratio. This means if your recipe needs 1 tablespoon of cornstarch, swap that out for 1 tablespoon of potato starch. It’s also worth noting that many cooks recommend adding root or tuber starches like potato or arrowroot later in the cooking process.
Besides, is corn starch and potato starch the same?
Like wheat flour, corn starch is a grain starch and potato starch is a root starch. Both starches produce a thickened liquid that is clearer than liquids thickened with wheat flour; however, potato starch will be the clearer of the two. Liquids thickened with corn starch will still be slightly opaque.
Likewise, how do you thicken with potato starch? The process is:
- Potato starch into an empty bowl.
- Add a little cold water and mix the two together with a fork or whisk.
- Slowly pour the slurry into the hot-but-not-boiling liquid, stirring to incorporate.
People also ask, what can I use as a substitute for potato starch?
You have a few starches to choose from besides potato—cornstarch, tapioca, and arrowroot—and they are pretty much interchangeable when you are baking with them. Sometimes even dried potato flakes can be a substitute for potato starch—yes, the kind in the box that you use when you want instant mashed potatoes.
Can I use tapioca starch instead of potato starch?
Like potato starch, tapioca starch can be used in place of wheat flour. When using tapioca starch as a potato starch substitute for thickening, note that its ability to thicken is slightly less than that of potato starch. Add an extra 1/4 cup for every two cups of potato starch that your recipe requires.
