2. After 30 seconds add bacon, cook for two minutes constantly stirring, then add apples and leeks. For an added zing add 1/4 cup calvados (Calvavdos was not in my 1978 recipe but I have since added it. Turn
heat to low medium. 

3. Cook for about 20-30 minutes until the mixture is a mush -- let cool.

4. Remove pork from marinade and carefully stuff in much - about 2 tablespoons per steak. More if you can get it in. Seal with toothpicks.
