Syrups, corn, dark

Dark corn syrup is a pantry baking staple best known as the base of pecan pie filling, where its thick, glossy body holds the nuts in place and sets to a chewy, not-too-firm texture once baked. Bakers also use it to keep cookies and cakes moist, to make candy and caramel corn since its high sugar concentration prevents crystallization and keeps the texture smooth rather than grainy, and to glaze hams or roasted vegetables for a shiny, slightly molasses-toned finish. Compared with light corn syrup, the dark version carries a deeper, more caramel-like flavor from added refiner's syrup, which is why recipes calling for a richer, more robust sweetness specify the dark variety.

A single cup weighs 328 g and delivers roughly 938 calories and 255 g of sugar, so recipes typically call for it in tablespoon or fractional-cup amounts rather than by the full cup. Kept sealed in a cool pantry, corn syrup has a long shelf life and rarely needs refrigeration, though it can crystallize slightly over time; a brief warm-water bath or a few seconds in the microwave restores its pourable consistency. Because it is essentially all carbohydrate and sugar with no fat or protein, it works purely as a sweetening and texturizing agent in baking rather than a source of any other nutrient.
