Epona here's basically what I do. It does change a bit every time I make it and I eyeball most of the ingredients. I serve it with rice or make a chow mein out of it.
Ingredients
Pork or Turkey mince
Szechuan peppercorns
Black pepper
Garlic
Ginger
Chillis or Chilli flakes (or both)
5 Spice (I don't like most supermarket stuff it's got to much star anise, so leave this out if you don't like that)
Stir Fry Veg (Pepper, onions, mushrooms etc)
Oyster Sauce
Hoisin Sauce
Dark & Light Soy
Fish Sauce (optional, it's kind of marmite and I can't imagine any dish cooked in Szechuan having this)
Chilli bean paste if you have it (definitely a Chinese supermarket ingredient)
Siracha or similar
MSG
Method
It's worth doing most of the prep before hand as it cooks so quickly. I normally stick my rice on when is I start preparing the veg.
I cook the veg and meat separately because even the big hob I've got doesn't kick out enough heat.
Stir fry the veg, even less then you might normally do.
Put them in a bowl out the way and wipe the wok
Add the ginger, garlic, whole Szechuan pepper corns and chilli's and cook briefly.
Add meat to pan. Put a pinch of 5 spice on and stir in as it cooks. If you've got an electric spice grinder or can be bothered to grind by hand, then I like to add freshly ground szechan peppers and black pepper for extra oomph. MSG if that's your thing.
When the meat is nicely browned add the veg back, I undercooked it in the first step as it will cook a bit more now.
Add the sauces. I tend to go quite heavy with the oyster and dark soy sauce. Hoisin gives a slight sweetness, but I don't use to much as my partner doesn't like sweet food, I like it as a contrast to the heat.
Serve and hopefully enjoy.
