150g ground peanut oil (use the vegetable oil if you don't have the ground peanut oil)
120g fine sugar (or just plain sugar is ok)
a pinch of salt
a pinch of baking soda
Egg wash : an egg yolk
Roast the raw peanuts in the oven for 15 minutes. Let them cool for 40 minutes. Remove the skins. Grind the peanuts but make sure that they are coarse, not smooth. We are not making peanut butter, remember!
Mix all ingredients together (minus the egg) in a bowl and gently stir the mixture until it turns into a cookie dough. The baking soda is used to make the cookies crunchy.
Make small balls and place them in a non-stick baking tray (or grease your ordinary tray with the oil).
Gently brush the egg wash on the balls. Then, use a drinking straw to make a light dent on the balls (skip this part if you wish).
Place the tray in the oven and bake for 13 minutes exactly.
Remove the tray from the oven and let the cookies cool down for at least 30 minutes. Enjoy your hard work!!!
