Tonight, Scott grilled up some burgers. I didn’t mix cheddar cheese into the burgers this time, but they still ended up mushy. Not oily and mushy, but still not what I expect a burger to feel like. One thing I’ve read is that you shouldn’t add salt until the burgers are on the grill. Also seems that freezing the ground beef can produce mushy burgers. In both cases, the problem is water being drawn out of the meat. We’ll have to try with not-frozen beef to see if that makes a difference.
