Unfortunately not available commercially in the U.S., this is a close approximation of Sainsbury’s Mixed Spice.
Mix together the following ground spices and store in a tightly sealed jar.
4 tsp. cinnamon
2 tsp. coriander
1/2 tsp. ginger
1/2 tsp. nutmeg
1/4 tsp. cloves
The list of ingredients on the Sainsbury jar puts ground dill seed (!) between coriander and ginger, in case you want to experiment with adding that to your mix!
