mongolian beef

Pack of beef stir fry strips
2 onions, sliced
3 tbsp cornflour
80 ml soy sauce
100 ml water
80 grams dark brown sugar
4 cloves garlic, crushed
2 inches ginger, grated
1 tbsp chilli flakes

Coat the beef in the cornflour and set aside.
Fry the onion, garlic and ginger in oil on the pan for 2 minutes. Add the soy sauce, water and sugar, stir until mixed and bring back to the boil. Pour off into a bowl and set aside.
Add some more oil to the pan and fry the beef for a few minutes, adding a little water if it sticks. Add the sauce back on, bring back to the boil, add more water if it's too thick, and serve on a bed of rice.
