Can you use baking powder in a pavalova instead of corn flour?

Baking powder is not a suitable substitute for corn flour in a pavlova recipe. Corn flour helps stabilize the meringue and provides a chewy texture, while baking powder contains leavening agents that can interfere with the delicate structure of the pavlova. For the best results, it's recommended to stick with corn flour or use alternatives like cornstarch if needed.
