Tacos are a blank canvas. With their increasing popularity worldwide and an enhanced interest in Mexico’s culinary history, tacos are experiencing something of a renaissance. Everyone’s jumping on the taqueria bandwagon and, as with any food item that captures public fascination, mutation and innovation are inevitable. Some pretty interesting tacos are coming out of this taco-obsessed moment. And while the argument for authenticity and the pitfalls of cultural misappropriation can certainly be made, people seem to be pretty laid back about the taco. It’s the new sandwich, the new pizza, the new DIY salad bar. You can put pretty much anything on a taco and maintain the moniker. Today’s Flank Steak Tacos with Chimichurri & Salsa Blanca are a celebration of this culinary freedom. A freedom we technically always had but I was once totally unaware of.

Fruit and Veg Pattern - Flank Steak Tacos with Chimichurri and Salsa Blanca

When I was young, I thought tacos came from a yellow box. I believed a taco had to be stuffed with ground beef, diced tomatoes and iceberg lettuce to be a called a taco. And I believed that the taco had to have a crunchy shell. If a flour tortilla was involved, the food item in question would be classified as a fajita or possibly a burrito, but definitely not a taco.

I know people say ignorance is bliss, but this is certainly not the case when it comes to tacos. If you had told my five-year-old self that I could put a piece of fried fish on a frickin’ taco, I would’ve attempted a back flip. Having said that, I probably would’ve failed… I wasn’t a particularly athletic child. These days, I’m much happier putting just about anything on a flour, corn or even a whole wheat tortilla and mowing down.

I’m kind of going through a bit of an Argentina phase. I spent the better part of an hour on Pinterest yesterday just looking at glamor shots of the country.

Really, these Flank Steak Tacos with Chimichurri were inevitable, it was just a question of when.

I added the Salsa Blanca after a somewhat fruitless Google search. I was looking for the name of the white sauce I ate at Santa Carne in Paris. I couldn’t find the name, but I did come across an interesting tidbit about the condiment habits of Argentinians. Apparently, they like their mayo, so I used the mayo-based Alabama white BBQ sauce as a jumping off point and added a few of the herbs from the cilantro chimichurri for continuity’s sake. I think I wound up with something fairly close to what I had in Paris, but it’s not quite there. The Salsa Blanca tastes really good at the very least. If you actually know what the sauce is called, please leave a comment below – I really don’t like being ignorant of such things.

It’s hard to let the pomegranate go, but fear not, they’ll almost out of season here, so I’ll have to get creative with my garnishes again soon enough. That being said, pomegranate and rich red meat are a match made in heaven. These Flank Steak Tacos are irresistible with pomegranate arils onboard.
