Krupuk udang (shrimp crackers) made of dried shrimp, tapioca flour, sugar, and salt is my favorite. They are sold as pinkish, flattened, hard disks. When deep-fried, they puff up into a curvy chip three times their original size and become super crunchy. Other types of krupuk include krupuk ikan (fish) and krupuk bawang putih (garlic). There’s also a special cracker made with the melinjo nut called emping.
Crackers, like sambal, are an indispensable part of an Indonesian meal. They are crushed over Gado Gado, or munched on between bites of Nasi Goreng.
