An aromatic spice rub is great to have on hand, and this recipe yields enough to share with friends -- in pretty jars, of course.
Combine all seeds in a skillet over medium heat, and toast, shaking pan, until aromatic, about 4 minutes.
Using a spice grinder, coarsely grind seeds in three batches. Transfer to a small jar. Add sugar, salt, and pepper. Shake well to combine.
The spice blend may be stored in an airtight container, at room temperature, for up to 6 months.
