The Indonesians have an entire world of fried crackers - krupuk - quite possibly the most variety in the world.
One that particularly stand out are called rempeyek. They are made with rice flour, coconut milk, spices and an extra ingredient.
The CC has seen the "extra" in the following variations - dried anchovies, peanuts, moong beans. Also, combinations of the afore-mentioned.
They are insanely addictive and not to be missed if you can find a local Indonesian market.
