what is corn flour versus corn starch

[kathy123]

Hi Everyone
I am making a chicken stir fry recipe from an English Magazine. It calls for corn flour.

Our local grocery store did not have corn flour but I have corn starch.

also what is corn starch. My niece is visiting from England. She is allergic to nuts, wheat, gluten and diary. Does Corn starch have gluten?

Thanks
Kathy

If it's an English baking recipe and they say corn flour, they mean corn starch. Corn starch is just corn kernels, dried and husked and ground... and I don't think corn has any gluten in it.
