Our local stores do not sell cornflour so I need a substitute.
Online I'm finding people saying use normal flour, or you can use arrowroot or you can use cornstarch at half the quantity. But these substitutions are given for purposes like thickening agents.
Really I don't know if something like 'flour' would be a good substitute in a Pavlova. What is the right substitute for the purpose of a Pavlova?
