Peanut Sauce / Sate Gravy

Ingredients:

1/2 kg Ground nuts (peanuts) - fry with a slight oil till cook
1 medium size onion - to be blended
3 cloves garlic - to be blended
1 cm ginger (halia) - to be blended
2 cm galangal (lengkuas) - to be blended
2 stalks lemon grass - to be blended
3 tablespoon of blended dried chilli
Salt
Sugar
Tamarind paste (Asam jawa)
Water
3 tablespoon oil


Methods:

Heat up oil. Pour in all blended items. Wait till it fume and crispy a bit. Meanwhile, blend the ground nuts but not to fine. It is best that you have 1/2 finely ground and 1/2 not too fine so that the gravy won't be that thick. Pour in blended ground nuts into the pots. Stir a bit. Pour in water. The amount of water is very much depending on the thickness of the gravy. Pour in some more water if you think the gravy is not smooth enough. Add in salt, sugar and tamaring paste. Stir once in a while to avoid the peanuts stick at the bottom of the pots. When you see the oil appear at the top and it already boil for a few times, the gravy is cooked.
