Can you use plain flour instead of cornflour in lemon meringue filling?

Yes, you can use plain flour instead of cornflour in lemon meringue filling, but the texture may differ slightly. Cornflour helps achieve a smoother, more delicate filling, while plain flour may result in a thicker and slightly less silky consistency. If using plain flour, be sure to cook it thoroughly to eliminate any raw taste. Adjust the quantity as needed, as plain flour may require slightly more than cornflour.
