Fry the dried anchovies until crispy, then set aside. In the same pan, fry the sliced jering until slightly golden and cooked through. Blend all the listed ingredients into a smooth sambal paste. Heat oil in a pan and sauté the blended paste until aromatic. Add tamarind slice, salt, sugar, and water, and let it simmer until the sambal thickens slightly. Stir in the fried jering and anchovies, coating them evenly with the sambal. Cook until everything is crispy and well combined. Let it cool before serving — perfect with rice or as a snack.
