Essentially, this makes Salsa Roja the Mexican equivalent of BBQ sauce: An all-purpose condiment with a secret recipe. Every Mexican grandmother has her own recipe and hence every family their own, “authentic” Salsa Roja recipe. In other words: as with so many other Mexican dishes and sides, there is no authentic, codified Salsa Roja recipe! To each their own! And thank God for that. This is exactly the beauty of this condiment. Every chef can (and should) tweak it to their own liking – as I have done with mine!
Mexican oregano is a dried herb used in Mexican cuisine. It’s similar in appearance to regular, Mediterranean oregano but is, despite its name, a cousin of lemon verbena rather than a member of the origanum family to which oregano belongs. It shares some of oregano’s unique and pungent earthy flavors and aromas but more subtly so with an added grassy kick of citrus and licorice. Mexican oregano is readily and cheaply available online and adds a unique element to Mexican dishes. If you can’t get Mexican oregano, you can substitute a pinch of marjoram or even regular oregano, just use a little less than the recipe dictates.
Hey Beth – sorry about that. The notes somehow went missing. I’ll add them again, but here’s a great article about canning salt. Basically, you can sub in kosher salt or even table salt (although use a bit less since the granules of table salt are finer)…it’s best to try to use a kosher salt without any additives (canning or pickling salt is pure salt without any anti-caking agents) if possible.
As you will notice when we dive a little further into these recipes, Mexican food has a stunning range of somewhat special ingredients. From Masa Harina, the essential ingredient of corn over a wide array of chilies either fresh, dried or ground to Mexican oregano and tomatillos. Some of these may at first glance seem foreign and difficult to come by, but fear not we’ll discuss the individual ingredients as we go and they’ll be easier to come by than you think.
