In a saucepan of boiling water boil the garlic for 15 to 20 minutes, or until it is tender but not soft, drain it, and discard the peel carefully, leaving the cloves whole. In a bowl whisk together the dill seeds, the fresh dill, the lemon juice, and the red pepper flakes, add the oil in a stream, whisking, and whisk the marinade until it is emulsified. Onto the end of each skewer thread a shrimp and 1 garlic clove. Arrange the skewers, shrimp end down, in a bowl just large enough to hold them. Pour the marinade over the shrimp, and let the shrimp marinate, cover loosely and chilled, basting them occasionally, for 3 hours. Drain the shrimp, arrange them in a shallow baking pan, and bake them in the upper third of a preheated 425°F. oven for 1 to 2 minutes, or until they are just cooked through. Serves 6.
