Try this:
1 clove garlic
6 spring onions
2 red chillies (I suspect it's the bird's eye chillies.)
1 piece stem young ginger
1 Tbsp. light soy sauce
2 Tbsp. plum jam (I think she mat refer to the Chinese version, not too sure.)
1 tsp. ketchup (or tomato paste)
salt and ground black pepper (surprisingly, I thought she would have said "white" instead of "black pepper".)
2 Tbso. light sesame oil
Crush garlic. Trim and finely slice spring onions. Cut chillies in half, remove core and seeds and finely chop flesh. Dice ginger.
Place garlic, spring onions, chillies, ginger, soy sauce, jam, ketchup, salt pepper and sesame oil in a small pan with 2 tsp. water and simmer together to make a hot, sweet sauce.
It's an approximation, but works for us...
