There's nothing worse than burger patties that fall apart on the grill! According to LeafTV, there are other simple ways to keep a hamburger together,  like limiting liquid ingredients so patties don't become too loose. LeafTv also warns not to overwork the meat or the patties may lose their stickiness. And to prevent patties from falling apart on the grill, patties shouldn't be flipped more than once or pressed down with a spatula.
