Here are three common spice blends that I’ve made over the years. It’s not that hard to create your own version. Most versions have the same ingredients in differing quantities.
Grains of paradise can be difficult to come by. I use a combination of cardamom and pepper to get a similar taste. If you live in the US it’s a bit easier to come by than in Canada, though I don’t know why that is.
Galingale is fairly easy to come by, as long as you don’t mind using the South-East Asian version of the spice. The version which is native to Europe has not been cultivated in several hundred years.
