Try this pickling spice recipe in your pickles instead of buying a pre-made pickling spice. Simply substitute this home made version.

The spices will be tied in a cheesecloth bag and cooked to release the flavors. Then removed before canning.

6 Tablespoons Mustard Seed
3 Tablespoons Whole Allspice
6 tsp coriander seed
6 whole cloves
3 tsp ground ginger
3 tsp red pepper flakes
3 bay leaves
3 cinnamon sticks

Crush the cinnamon sticks into pieces and crumble the bay leaves.
Combine all ingredients and store in an airtight container.

Makes approximately 1 cup.

Use in your pickle recipes as directed.

These ingredients can be adjusted according to taste. If you wanted to make a spicy pickle you could add some more red pepper flakes. Or if you don't want any spice you could leave them out.

That is the beauty of a home made recipe. You control the flavors. Experiment and see what you come up with.
I must add that I priced seasonings from a super market and I don't really know that this would be any less expensive that just buying the spices already mixed.

BUT if you have access to spices in bulk. I'll bet you could make your own more economically.
