Mexican Oregano (lippia graveolens) differs from Mediterranean Oregano in a handful of ways. It possesses more citrus notes being that it comes from the verbena family (think lemon) rather than the mint family. Mexican oregano tends to be stronger and earthier, fitting dishes with tomato and chile bases. It lends itself to Mexican and Tex-Mex cuisine rather than Mediterranean cooking. We are fine tuning a chorizo recipe that isn't quite the same without this particular species of oregano!
Rancho Gordo is based in Napa and works with small farmers in Mexico to carry on the cultivation of indigenous crops. Their primary focus is heirloom beans but they also work with farmers to grow spices, salt and corn that are inherently suited to their growing regions.
