To prepare bouquet garni, combine first 4 ingredients in a small bowl. Divide mixture evenly among 4 packages of a double layer of (4-inch-square) cheesecloth. Gather edges of cheesecloth together; tie securely with kitchen twine.
Place 1 bouquet garni, 1 cup rice, 1/4 cup lentils, 1 tablespoon ginger, 1/2 teaspoon cumin, and 1/4 teaspoon white pepper in each of 4 containers. Seal tightly.
