I scanned the Food Glossary, which is a really nice feature, but I didn't find an answer...

I had breakfast from the food carts in the Zocalo in Playa and saw on the "counter" a bowl filled with liquid of a broth consistency. In the liquid were, as best as I can recall, peppers and onions. It look dangerous. So of course I picked up the ladel and added it to my breakfast. It numbed my lips. I am not exaggerating. Yet, it didn't seem to numb the inside of my mouth, because I could taste it. And it was yummy.

Does anyone know what it is named? What it's made of?
