Good Burger Press

The press I received as a gift and since then has often used. The press works very well with beef from the butcher. The press is not previously oiled or greased. Meat from discounters (or pure ground pork) usually sticks easily fixed only and can hardly form. After use is to clean the press in the sink, dishwasher, I have not dared.
I fill usually about 110 to 130 g in each side that are then fine Patty. Prior to molding, I'm considering some blanks baking paper rightly, the Pattys may be stacked nicely without too much space do not need to.
