Chilli Ginger Sambal

This is an Indonesian sambal, delicious with most South East Asian dishes. There are a lot of chillies in this recipe, but don't be put off.  Those fat red chillies you buy in the supermarket or at the grocer's (or grow in your garden like I do), are mild.  You don't even need to deseed them. And the vinegar (or lime juice) dampens the heat further anyway.

3 cm piece fresh ginger, peeled and chopped
10 fresh large red chillies, or to taste
a good dash of white vinegar or lime juice
chicken stock to moisten

In a mortar or a food processor, grind the ginger and chillies into a rough paste.  Add a little lime juice or vinegar and salt to taste, and moisten with chicken stock.
