I've noticed that the recipes on the curry paste and stir fry sauce containers I get always start with adding the meat first and the vegetables later. I know from experience that over cooked game meat is tough and can taste 'gamey'. So I've come up with my own technique for when I use game meat in a curry or a stir fry. The last 2 meals I cooked were a curry and a stir fry (pictured above) and I made both with mountain goat. Mountain goat is known for being tough but the meat in both my meals was tender!
Anyway, my basic technique is to cook the meat first and then add it back in at the end. But I do a few other things that might make a difference too. Here is my technique step by step.
1) Thinly slice the game meat (and do not use calf, shank or some other 'stew' like cut - I prefer shoulder, small 'flat' roast, or backstrap).
2) I then add a teaspoon of salt, pepper, a teaspoon of sugar, and rub in the red curry paste (a healthy tablespoon or more) - for stir fry I usually use 'chili garlic sauce' and I rub that in too. Then I leave the meat on the cutting board to soak up the flavors. I might leave it an hour or so while I get all the other vegetables ready.
3) Preheat the oven to 170 (my oven's lowest setting) and put a glass container in there.
3) Heat up a cast iron skillet (or what I use a Le Creuset pot), add oil (my favorite is chicken schmaltz but usually grapeseed or avocado oil) and quickly saute the meat. I do not cook it completely and actually take it out looking a little raw and put it into the preheated glass container in the oven. Then I turn the oven off, but the meat continues to cook in the pre heated glass container and warm oven. Basically I am doing a sort of 'sous vide' slow cook style.
4) I then cook the onions, carrots, garlic, peppers, broccoli, celery, etc (in that basic order). Don't over cook the broccoli!
5) For curry I'll add the coconut milk when the vegetables are mostly done, heat a bit to warm up the milk, and then add the meat just before I serve it up.
6) For stir fry I add the meat back at the end and then add a half cup of water/chicken stock and soy sauce mixed with a teaspoon of corn starch. This thickens up into a sauce and finishes the meat.
And that's my basic stir fry or curry technique!
