How to use a mortar and pestle?
· Place the food in the mortar (bowl) in small quantities;
· Use some downward pressure over the food with the pestle (pounder);
· With hard foodstuffs, like peppercorns and even pills, move the pestle back and forth over it with some pressure until it breaks up;
· Turn the pestle in a circular motion around the mortar, maneuvering it back and forth with a bit of pressure over still unbroken pieces.
It doesn't take long to get used to using a mortar and pestle.
- Choose the least absorbent materials when you need purity in what you crush.
- Choose the most absorbent when you want the flavor to carry on to the next batch that you grind.
- Choose the size based on the size and quantity of the ingredients
