Japanese Curry, Again

I tried to make Japanese pork curry again. The flavor is good as always, but it still wasn't as awesome as my last batch. The meat is too hard this time. Once again I coated the meat with soy sauce and corn starch, but I think the problem was with the cooking. The fire was around medium instead of high. There was a lot of oil at the bottom of the pot. The meat didn't stick onto the pot like last time even though I didn't move it around too much. The end result was the meat not seared and browned properly. Oh well, I'll try again next time.

The last batch is quickly becoming the "dream" curry if I don't figure out how I cooked it that time.
