I recorded the weights of the spices I used last time I made a blend. It made a ton, so you could probably cut the numbers by 5x. But this is a pretty good blend, and you can adjust it how you like with whole numbers. - 100g green cardamom seeds (no pod) - 66g black pepper - 12g cinnamon - 6g nutme...

You can use preground spices too, to make the blend. But because they're a fine powder, you'd use less per cup. Coarser grinds you can use more of and boil longer with more water.
