Theoretically............no. The operative word in your response is "somewhat." There is no somewhat in cooking. There is the proper way and then there are all the other ways.
The texture of the ground meat is critical. You are not making paste here, it's hamburger!!! A meat grinder is $30. You can use it to make sausage and other good stuff. Buy one. Or send me your frikkin' ribeye, and I'll grind it for you.
