Ingredients:

2 # of ground lamb
1 large onion (chopped fine with water/juice squeezed out)
1 Tbl of Marjoram
1 Tbl of rosemary
2 Tbl of salt
1 Tbl of garlic
1/2 tsp of ground pepper

Process onion until it is very finely chopped. Wrap it in a tea towel and squeeze out all the juice. Put lamb and onion and spices in food processor and process until everything is well mixed and pureed.

Stuff it into a loaf pan and cook until 165-175 degrees in a water bath of about 1" of water in a pan (put boiling water in the water bath so it doesn't take forever to warm up). It took about 1.5 hours for my gyros to cook at 325'.

AB has you putting a brick on top of the loaf to make it denser, after it comes out of the oven. I didn't, it was fine without it. I let it set for 15 minutes before slicing but I did drain off the liquid/fat.
