This recipe is definitely worth buying the individual spices for. I like to make a trip to Penzey's in Pittsburgh's Strip District for my seasonings. You can buy in varied quantities. Keep your old spice jars and refill as needed (Penzey's sells in bags).
1 T yellow mustard seeds
1 T allspice berries
1 T dill seeds
1/2 T whole cloves
1 dried red chile, crushed into little bits
3 cinnamon sticks, crushed
3 bay leaves, crumbled into little bits
1 teaspoon black peppercorns
1/2 star anise pod, crushed (omit if using fennel seed)
1 teaspoon fennel seed
I love this recipe. It really beats McCormick's pickling spice. The fennel is optional, but gives the pickles a slightly unique flavor. I sometimes opt for a bit more cloves too, but be careful as they can overpower the pickles.
