Combine flour, instant yeast, sugar, salt, dill weed, dill seed, onion flakes, and granulated garlic in the bowl of a food processor that has been fitted with a blade or dough blade. Pulse 10 times. With the food processer running, pour the water and sour cream into the feed chute. Continue processing until the dough forms a cohesive ball. Spin the dough ball 20 times and shut off the food processor. Remove the dough, form a smooth dough ball and place in a lightly oiled mixing bowl. Cover with a clean tea towel and let rise in a warm place for 15 minutes.
