1. In an 8- or 9-inch skillet heat 1 cup oil over moderate heat until hot but not smoking and fry shallot, stirring, until golden, 1 to 2 minutes. Transfer shallot with a slotted spoon to paper towels to drain. Fry garlic in same hot oil and drain in same manner.
2. In a small bowl stir together tamarind and warm water, mashing tamarind gently, and strain mixture through a fine sieve set over a bowl, pressing hard on solids. Stir in fish sauce, vinegar, sugar, and water.
