I have a meat grinder and I’ve been seriously toying with the idea of making my own burger from good lean cuts of beef . People used to do it all the time and I think it’s the only way that burger can be certified kosher .I think that I NEED to get a meat grinder; one with a hand crank would be fine. I was thinking that a mix of chicken and pork ground would make for a really good burger. Another thought would be using left over corned beef or roast and grinding for a burger. Also would be interesting to use a grinder to make sausage as you can grind twice with the second grind adding the spices.
