Cinco de Mayo. Let’s get after it with these Ancho Chile Fish Tacos.
I’m obsessed.
Maybe it was those awesomesauce steak tacos I had at Hugo’s a few weeks ago. Maybe it was all the Chipotle I ate at Stagecoach. Maybe it’s also because I realized Mexican food is my #1.
Since it’s Cinco de Mayo, I’m sidestepping the Middle East for the day and instead sharing my recipe for Ancho Chile Fish Tacos.
What is Cinco de Mayo?
A little history: In case you thought Cinco de Mayo was just National Margarita Day, you are wrong. It’s actually the anniversary of the Battle of Puebla, when Mexican forces defeated the French forces of Napoleon III back in 1862. While France’s presence in Mexico lingered for another five years, victory on that particular day symbolized Mexican resistance to foreign dominance.
Pretty good reason to celebrate, so go ahead and raise that glass.
Inspired by the menu at Chicago’s finest Mexican food establishment (Frontera Grill/Topolobambo by Rick Bayless. You may have heard of him…he’s kind of a big deal), I came up with a sauce with a little kick, a little sweet and a whole lotta flavor. As a salad dressing or a marinade, you really can’t go wrong with this. Unless you decide NOT to try it. That would be wrong.
What are Ancho Chiles?
Ancho chiles are a mild chile known to have originated from the Mexican State of Puebla. You may know them better as poblano peppers, which is what they are when fresh!
What ingredients do I need to make Ancho Chile Fish Tacos?
- Fish (duh), I used a tilapia here, any whitefish would do
- seasonings, the traditional Mexican ones (cumin, allspice, oregano)
- corn tortillas, because corn >> flour
- dressing ingredients, to give it all glisten – onion, garlic, orange & lime juice, mustard, child powder and cilantro
- avocado, because why not
What’s the difference between Greek and Mexican oregano?
* The Kitchn explains the difference between Greek/Italian or “Mediterranean” oregano and Mexican: Greek oregano, aka wild marjoram, is savory and earthy, while Italian is milder and Turkish is more pungent. Used in dishes with strong flavors. Mexican oregano, on the other hand, grows in Central and South America and is sometimes referred to as Puerto Rican oregano. Although this herb shares the basic pungent flavor of Mediterranean oregano, it also has notes of citrus and mild licorice. This pairs well with chile peppers, cumin, and paprika. Thanks to The Spice House, I can get both readily and my pantry is fully stocked.
