- Once they are cool, put the seeds in a
spice grinder or the dry jug of a
powerful blender, such as a Vitamix.
You may need to grind them in small
batches, depending on the size of your
grinder. (No need to sift.) Store in an
airtight container for up to six months.
Note: If you don’t have a grinder, a
Vitamix blender, or a mortar and pestle,
place the roasted whole cumin between
two paper towels and roll over the top
sheet with a rolling pin. Press hard and
continue to roll until you have a fine
powder. This is best done in small
batches.
