If you use whole cardamom pods, then you need to pick the seeds out and grind them smaller using an electric spice grinder or mortar and pestle.
Then measure all your dried spice powders into a jar and mix them together. The total amount makes 6 tablespoons of spice mix. It fits for example in a half-cup mason jar.
Notes
If you can find bitter orange peel as a dried powder, that is also a common ingredient in Finnish and Swedish gingerbread mixes. You can add 1-2 teaspoons of pomeranssi, pomerans in addition to the other spices.
