Flour in a sack.
The Integral Flour Trick For Crispy Potato Patties
Getting a crispy surface on your potato patties can be tricky, but it can be made easier by dredging your patties in a mix of all-purpose flour and rice flour.
Flours with a high protein content, such as all-purpose flour, also have a higher gluten content. Gluten sucks up moisture and can make a crunchy golden crust tough.
Rice flour has no gluten, so using it when dredging helps to reduce the overall gluten level. Rice flour mixed with cornstarch will give you a perfectly crispy potato cake.
This flour trick works well with potato cakes as well as anything else you want to dredge and fry up. So, the next time you are creating a dredge, don't forget the rice flour.
