Divide the meat in four equal parts and form each portion of meat into an oval or round shape patting it down slightly. Set patties to the side and heat up skillet. Once you got your pan HOT, add all four patties and cook for about four minutes lowering heat a bit as not to burn meat. Flip over & cook till desired doneness..like cooking hamburgers, if you like it rare then don't cook too long( about 3-4minutes per side.) Cook longer for well done. If you choose to eat the loco moco with egg, cook each egg sunny side up in one tbs butter.

For the gravy:Melt 2 TBS butter in a pan & sautee the mushrooms for aprox 5 minutes. Add the beef broth, dash of salt & black pepper & about a teaspoon of Worcheschire sauce. Bring to a hard boil, meanwhile take the 1 tbs of cornstarch & put it in a small cup or bowl add 1 tbs of water to make a paste & add to boiling broth. The cornstarch slurry will thicken the broth making a slightly thick brown mushroom gravy. At this point you can decide if you want a thicker gravy which you can achieve by adding another tbs of cornstarch mixed with water again & adding it in. Add more salt & pepper if needed to taste.
