This record covers skordalia in its condiment role: the garlic-potato sauce used as a spread inside Greek sandwiches and wraps rather than served as a side on a plate. The distinction matters. As a table dish it stands alone next to fried cod or beetroot; as a condiment it is a working component, judged not by how it eats off a spoon but by what it does to the bread and the filling around it. This entry is about that job. It is national, applied cold, and most at home against fillings that are fried, fatty, or assertively grilled and need a sharp counterweight.
In use, the order and the amount are the whole craft. The sauce is spread on the bread, not spooned over the filling loose, because its dense emulsified body is what lets it grip the crumb without sliding. A thin, even layer on the cut face does the work; a thick gob does not. It pairs hardest with fried fish, fried vegetable fritters, and rich grilled meat, where its raw-garlic punch and oil cut straight through fat. Good condiment execution means a paste stiff enough to stay put under the filling, garlic strong enough to register through a heavy partner, and just enough acid to brighten rather than weigh the sandwich down. Sloppy execution is a loose, weeping skordalia that soaks the bread to mush, too little applied so it disappears behind the filling, or so much raw garlic that it flattens everything else in the sandwich. The single most common condiment failure is using it too wet, which turns the bread structurally useless.
How it shifts as a condiment follows the filling it serves. Against fried bakaliaro or fritters it goes on assertively, since the fried element can take the garlic head-on. Against milder fillings it is laid thinner, used as a sharp accent rather than the dominant note. Some builds thin it slightly or cut it with the filling's own juices so it spreads further without going slack. The sauce considered on its own, its base, its emulsion, its texture as a standing dish, is documented separately and deserves its own article rather than being crowded in here. As a condiment, skordalia is judged by one question only: does it stay put and cut the fat without drowning the bread.
