The key to producing light, lacy rempeyek is to slowly ladle the batter on the side of the wok above the oil line. For this reason you want to use a gently sloping wok. For a demonstration of how to do this, watch this video, which also provides a slightly different recipe.
Rempeyek Kacang--Peanut Crisps
(recipe adapted from Indonesian Food and Cookery by Sri Owen)
250 grams (8 oz) peanuts
2 kemiri (candlenuts)
2 tsp ground coriander
1 clove garlic
1 tsp salt
1 cup water
120 grams (4 oz) rice flour
vegetable oil for frying
Pound the kemiri, coriander, garlic, and salt in a mortar until you have a fairly smooth paste. Mix the paste with the rice flour and then slowly stir in the water. You should have a fairly thick, cream-like batter.
Lightly pound or chop the peanuts. Some people like bigger pieces; my wife insists they should be coarsely ground.
Heat the oil in a wok to about 350º. Sprinkle several teaspoons of peanuts into a ladle of batter. Draw the ladle around the side of the wok above the oil. You are aiming to form a thin skin of batter just above the oil. After about thirty seconds, nudge the peyek off the wok into the hot oil. Cook for a minute or so, and then carefully lift the finished crisp out of the oil and drain on paper towels.
As long as you don't live where there's high humidity, the crisps should last several days stored in a cannister--if you can keep yourself from devouring them.
An even lighter crisp can be made with bayam. Simply dip the leaves in the batter and fry.
If you use ikan teri (ikan bilis), cut back on the amount of salt in the batter.
