Know Your Oregano
If your recipe calls specifically for Mexican oregano, I recommend that you try to access that variety, which is usually available in Latin American markets. It is not the same as the Mediterranean version, known as Origanum vulgare. Although there are different types of Mexican oregano, most belong to the verbena family. Mexican oregano is sun-dried and provides a similar but more robust flavor than its European counterpart; it has strong citrus notes.
