You can us this simple recipe and then add whatever you have lying around to add more to it.
Whilst I cook most things using all fresh ingredients I also keep a selection of prepared items if I'm in a rush. These include jars of crushed garlic, chopped chilli, grated ginger pre-cooked noodles. Occasionally coriander, but I always prefer fresh when I remember to pick it up.
Step 1: Ingredients - The Base
500ml stock (I use chicken, but vegetable or Dashi would work just as well)
pinch of sugar, preferably soft brown or palm to balance any spice and add a rounded flavour
a whole star anise
1/2 teaspoon of grated ginger from a jar
1 teaspoon of Soy Sauce
Some fresh coriander (or pre-prepared in a jar)
