Sanguchon is a Bay Area food truck providing Peruvian street food, and I was excited to try their wares. At a glance, the Pan con Chicharron seems like an extraordinarily appetizing sandwich. Sliced pork loin joins fried yams, salsa criolla and aji rocoto aioli on a roll baked (they say) exclusively for their truck. Those aren’t ingredients you see every day, and though I enjoy a good torta, too much of anything gets old. Salsa criolla is a salsa with a red onion and cilantro base, and aji ricoto is a chili pepper with more heat than a poblano but not as much as hot jalapeño. So you’ve got savory pork,  a crispy sweetness in the yams, a sharp salsa corralling things a little heat playing over everything. That’s a potentially great sandwich, and I strongly suspect that there are days when the sandwich Sanguchon serves lives up to that potential. Sadly, the day that I got my hands on it it failed to meet its mark. I will say that the bread was very good, chewy and with a flavorful crust. There was no disappointment there. I have neither a strong affinity for nor a strong grudge against food trucks,  but I can’t help but wonder if the fact that this sandwich came from a truck had a lot to do with inconsistency. There’s an urgency in serving food from a truck, especially when it’s busy (and it was busy.) People stand around waiting, it doesn’t lend itself to conversation or nursing a drink, and so you want to get them their food as fast as possible. Sometimes that means the food comes out terribly unbalanced, with large, meaty pieces of pork crying out for salsa and aioli, yams delightful when present but unaccounted for in far too many bites. Had someone taken a bit more time putting the sandwich together I suspect it would have been a very different result. Alas, one cannot dine on possibility. It is reality we dig in to, and the reality at Sanguchon was a disappointing sandwich.
