Last weekend my family had a craving for take-out pupusas and I insisted we try La Santaneca (on Mission Street going south past Cortland). I remember we used to go there a lot when I was younger and I was curious to see how they stood up.
The pupusas were not super greasy or soggy. They managed to stay fairly firm by the time we got home. I think I am a typical American (or is it Californian??!) in that super greasy things kind of turn me off, but these pupusas were not nearly as greasy of the ones I've had elsewhere. We had cheese and mixtas (cheese with chicharron - fried pork). I don't know that I can describe the masa very well since I am not very knowledgeable about the dough (or pupusas for that matter!). Of course, they were accompanied by curtido (cabbage slaw).
The horchata was excellent. My mom noted that it was incredibly chocolate-y, which is an ingredient that many pupuserias skimp on. The serving size of the small horchata was very small.
I know that there is/was another Santaneca on Mission St. between 24th and 25th, but I don't know how it compares to this joint.
