The sauce in Mexican food and especially in tacos is considered as the soul, this is because if you have a truly tasty sauce it can elevate and complement the flavors of the stew and give you the perfect dish. Even someone described it with this wise phrase: “...the sauce is so effective that elevates the category of good, corrects the insignificance of mediocre and hides the ordinariness of bad...”
Although sauces are the backbone of Mexican cuisine, we can find spices from all over the world such as garlic, cilantro, onion, pepper, etc. However, there are 2 ingredients that cannot be missing in the preparation of a sauce, which are very Mexican. Of course, one of them is some variety of chile, which can be in different states such as fresh, dry, with or without seeds, roasted, fried, or however you like, the important thing is that it must be there to give that spicy touch that a sauce needs.
The second ingredient that accompanies the chile is a fruit that has been present in Mexico and its culture since the Aztecs. This is the xiomatl or translated into Spanish the jitomate -red tomato- or the tomatillo, which is a green tomato with a sweeter and more acidic flavor at the same time, which sadly is not so easy to find in Europe.
Just as it was mentioned before that chiles can be in different states, the sauce can also be made with different methods. Some prefer to make raw sauces simply by grinding the ingredients in a molcajete - which is a stone mortar - or to cook them and blend them, but this depends on your tastes or the specific use of the sauce, as we have dishes that are usually served with a particular one like barbacoa with the “drunken sauce.”

There are countless sauces, although the most common are red sauce and green sauce, and even within these 2, each Mexican household's recipe can vary a bit. Most people believe that all sauces are spicy, but that's not true since they can be made with many chiles or with varieties of them, less or more spicy depending on what is desired. Now that you know this, you can imagine the great variety of existing sauces and those yet to be created, as there are some that even have peanuts, pulque -fermented alcoholic drink- or even ants in them, the trick is to get creative!
Here I will leave you some recipes so you can prepare your red and green sauces and experiment with the drunken sauce and some barbacoa tacos.
