Mortar and pestles are usually made in a matching set. The mortar is a small bowl and the pestle is a wand with a curve that's perfectly shaped to grind smoothly against the mortar. The instrument may be made from wood, stone or ceramic, and you'll want to choose your material based on your culinary needs and personal preferences. Ceramic mortar and pestles are capable of grinding spices very finely, but they're also more fragile than other types. Wood mortar and pestles are durable, but they're also slightly porous, and subject to stains. It's also possible for the flavor of one spice to stay present in the mortar between uses, tainting the flavor of the next spice you grind. Stone mortar and pestles also grind very finely, but unless they're conditioned properly, fine particles of stone can get ground into the spices. Do you want to crush large amounts of spices, seeds, and nuts, or only small amounts? You will find varying sizes from palm size to bowl size, and it may even be handy to have two different sizes if you have the space and budget for it. If you plan to grind a very large amount of spices, getting a spice grinder may be more suitable for your needs. A mortar and pestle is best for just enough spices to create whatever dish or spice mix you immediately want to use.
