A recipe from the 'net.
This seasoning can be used for a lot more than just tacos, it is excellent as a seasoning for mince for pasta dishes for example.
The calculator above can scale the recipe, just complete one of the yellow fields and hit ENTER or SPACE, and the rest will be calculated.
Place the ingredients in a spice grinder (you can also use a coffee grinder) and grind them to the consistency of finely ground black pepper.
Store the spice blend in a tightly sealed container, away from excess light, heat, and humidity, for up to 3 months.
Brown 500g of premium beef mince in a pan, then add a little water and stir in 10-15g of the spice mix (20-30g/kg). Cook for a total of 20min keeping just a little free water. Then mix a little cornflour with water and add enough to bind the free water to make a coating rather than runny gravy. Remove excess fat. Adjust the amount of chillie to taste, and add salt to taste (about as much as the weight of oregano might be a good start).
