3-4 Thai bird's eye chillis (we like this really spicy, if you think you can't handle it then scale back the chillis)
1 tablespoon nam pla (Thai fish sauce)
1 tablespoon oyster sauce
4 tablespoons Thai sweet soya sauce (this ingredient is key to this dish. Try really hard to find a bottle, it's not like standard soya sauce as it's very thick and syrupy)
2-4 tablespoons water
1/4 teaspoon MSG (yeah, I know...)
Instructions
Remove the fat and cut the steak into strips
Roughly dice the onion
Crush the garlic
De-seed the pepper and cut into strips
Thinly slice the fat red chilli(s) - remove the seeds if you want it less spicy
Roughly chop the Thai bird's eye chillis
Add a tablespoon of oil to a frying pan or wok and quickly stir fry the onion and garlic for a couple of minutes
Stir fry the beef and peppers for a couple more minutes
Add the chillis and fry for a minute or so to release the flavour
Add the oyster sauce and the nam pla
Add the Thai sweet soya sauce and loosen the 'gravy' with the water. Simmer for about 30 seconds. Don't over-cook at this stage, there's supposed to be a decent amount of gravy to soak into the rice
Serve with Thai rice and some chopped Thai basil or coriander / cilantro on top.
