Salsa de Molcajete
Salsa de Molcajete refers to a salsa that is ground by hand in a molcajete, Mexico's version of the mortar and pestle. Nearly all salsas used to be prepared this way, but now many cooks use blenders and food processors. Because of this, even in Mexico the term evokes nostalgia for the handmade quality of bygone days. A few restaurants in Mexico City prepare Salsa de Molcajete table-side in a collaboration between the chef and the customer. Here are some basic ingredient suggestions, most of them available in the United States. They are followed by a sample recipe.
About the recipe
At Mexico City's historic cantina, El Belmont, the chef places a tray on a table beside the customer. On it are a molcajete surrounded by a host of colorful, fragrant ingredients: chiles, herbs, spices, garlic, onion, peeled tomatoes, water, limes, and one of the concoctions's secrets: toasted sesame seeds. While they are regularly used in different moles, I had never seen them incorporated into so many salsas. In the proper proportion (moderation), they add a crunchy texture and an earthy roasted flavor to the salsa. After an initial consultation with customers, the chef begins to add and grind the ingredients, one by one. As the process continues the molcajete slowly fills and emits the intoxicating smell of its diverse ingredients.
Suggested ingredients

Salt
Garlic
Chopped onion
Toasted Sesame seeds (heat them in an ungreased skillet over medium heat, stirring often until they are golden brown)
A selection of dried chiles, such as, anchos, pasillas, pequíns and tepíns. Break the larger chiles into small pieces and cook them over medium heat in just enough oil to film the surface of a skillet. (also see below)
Fresh chiles, such as serranos, jalapeños and poblanos. They should be roasted or boiled as described below, seeds removed, if you wish, and cut into manageable pieces
Canned chipotle chiles and/or their adobo sauce
Tomatoes, roasted or boiled until the tomato skins can be removed and they are reasonably soft
Tomatillos, also roasted or broiled, but they do not need to be skinned
Cilantro
Limes to provide juice
Oregano
Mint
Tips and Directions
Add a little water to thin the salsa, if necessary.
If you cannot find a molcajete a rough-surfaced oriental mortar and pestle will work.
Make sure everything to be added to the molcajete can be easily ground. Dried chiles should first be fried in just a little oil until they are crisp enough to grind easily, but care must be taken not to overcook them, which will make them bitter. Smaller ones such as the chile pequín or de árbol can be added whole, but larger ones like anchos and pasillas should be broken into small pieces. Fresh chiles should be roasted or broiled to make them soft and to facilitate removing their skins.
Roasting can be done either in an ungreased skilled over moderate heat, or they can be placed under a broiler until soft and slightly blackened.Tomatoes should also be roasted or boiled until fairly soft and the skins removed.
Adding a little salt to the molcajete will provide a coarse texture that will make grinding harder items such as garlic and onions much easier.
