Falafel Sahyoun is the Beirut house style of falafel sandwich associated with the Sahyoun name, a Damascus Street institution that famously runs as two adjacent, competing shops bearing the same family name, each turning out its own version of the same sandwich. It belongs in the catalog as a named, place-specific form rather than a generic falafel wrap. The angle is consistency at volume. This is falafel made by a kitchen that fries continuously for a steady line of customers, so the sandwich is defined less by an unusual ingredient than by the discipline of doing the standard build the same way every time: fritters from a settled recipe, sauce mixed to a fixed consistency, pickles and herbs in a set proportion, rolled fast and tight. Done right it is a sandwich that tastes the same on a Tuesday as on a Saturday. Done wrong it is an off batch, oily or pale, that betrays how thin the margins are.
The build is the classic Lebanese falafel sandwich executed with a practiced hand. Thin Arabic flatbread is laid out, a tahini sauce sharp with lemon and garlic is applied as the base, and the falafel goes in hot, often pressed slightly so it nests and catches the sauce. The garnish is the recognizable Sahyoun-style array: tomato, fresh mint, pickled turnip and sour cucumber, sometimes radish or other house pickles and a touch of chili, kept in proportion so no single element overwhelms the chickpea. The bread is rolled tight, frequently into a slim cylinder that holds its shape in one hand, and sent out fast while the fritter is still crisp. A good one shows a shell that crackles, a green moist crumb, a tahini coat that is nutty and lemon-bright, and pickles sharp enough to cut the fry. A sloppy one arrives with the falafel gone soft from sitting, the sauce pooled, or the pickle balance off so it skews sour or flat.
It varies first between the two competing Sahyoun storefronts themselves, each of which keeps its own recipe and its own loyalists who will argue the differences in spice, sauce sharpness, and pickle mix. Beyond that it varies the way every falafel sandwich varies: the chickpea or chickpea-and-fava base, the heat of the chili, the option to add fries or hummus, the choice of thin flatbread or a thicker pocket. Each of those additions is a recognizable form in its own right and deserves its own treatment rather than a footnote here. They all return to the same idea: the standard sandwich made reliable by a working kitchen, judged on whether the batch in your hand is as good as the last one.
