La Casa de Samuel in Chicago and El Hidalguense, which specializes in goat cooked over live coals, in Houston another.
That style of condiment is quite common in Jalisco. During our visit to Puerto Vallarta, it was ubiquitous.
Learn new things all the time around here. Can't say I've run into the oily salsa at Casa de Samuel or in Purto Vallarta, but definitely more curious about it. Any other field research on oil based salsas?
We opted for La Oaxaquena last night, which was a pleasure for my guests and myself, as I hadn't been there in a year and a half. The stars of the show were the table salsas, each so distinctive, yet all exhibiting a pleasant burn. The creamy one is my favorite- some have said ground pepitas give it its richness, can anyone vouch for this? Guac was a little salty, but deliciously in the chunky camp, full of cilantro and jalapeno. I don't think you can go wrong with melted cheese and chorizo married in a puddle of deep orange grease- the casuelita appetizer was sublime. Ensalada Oaxaquena was built on a think foundation of iceberg, which I could have done without, but the nopales were smoky and tangy without the least bit of typical slime and strips of queso fresco provided a great creamy counterpoint. My entree of enchiladas Oaxaquenas was decent, but the shredded white meat- only chicken was dry and the mole had a burnt chile bitterness that was much mellower in my companion's half chicken with mole, which I attribute to the fortification of the sauce with the chicken's juices. My other companion's enjitomatadas were probably the most authentically Oaxacan dish of the night, sprinkled with very salty queso cotija. I also had a bite of a cesina taco that was quite mind-blowing, charred, salty, and perfect, another taste of Oaxaca. All-in-all a great meal, I really impressed the out-of-towners with another example of Chicago's great regional Mexican offerings- "can't get tacos like these in Ann Arbor". And my friends really liked the $4 margaritas too!
