⭐ Potato Starch (Best Gluten-Free Option)
1:1 (1 tablespoon potato starch per 1 tablespoon cornstarch)Potato starch is a fine powder that gelatinizes at a similar temperature to cornstarch, making it an effective thickener and binder in burger mixtures. It helps retain moisture and improves the patty’s cohesion by absorbing and holding water.
To use potato starch successfully, mix it evenly into the ground meat and other ingredients to ensure consistent binding. Avoid overheating as excessive heat can degrade starch properties, but typical burger cooking temperatures are suitable.
Compared to cornstarch, potato starch yields a similarly tender and juicy burger with no off-flavors, making it the closest functional match in burger recipes.
