I discovered this when my ex exposed me to it. Her cousin had been incarcerated and in prison this is something they had. Once he got out he swore by it. We could only find it at one store and it was maybe $1.47 (pre covid). These days it's hard for me to find, but I can get it as a two pack on Amazon for $10. It's well worth it in my opinion. Not overly spicy and has great flavor. I love it on taco salads and tacos in general. I've tried other green sauces like La Victoria and anything else that looks similar, but none compare. If you can find this, I highly suggest trying it out. You'll forever make it a staple with all your Mexican cuisine.
