Can you use cornflour instead of plain flour in hamburgers?

Cornflour, also known as corn starch, is not a suitable substitute for plain flour in hamburgers. Plain flour, typically made from wheat, provides structure and binding properties to the hamburger patty due to the presence of gluten. Cornflour, on the other hand, lacks gluten and would not achieve the same binding effect. Substituting plain flour with cornflour may result in a crumbly and less cohesive hamburger patty.
