How do you do this: To use a mortar and pestle
Fill the mortar no more than one third full with your raw spices. Hold the mortar in place with one hand, take the pestle in your opposite fist, and twist it against the ingredients in the mortar so that they are ground against its bottom and sides. Evenly grind, bash or crush all of the spices, using the pestle to mix and grind them until they are all reduced to the same consistency. Continue until the ingredients are as coarse or fine as you want.
