Currants

One US cup of currants weighs 144 grams. Going the other way, 100 grams is about 0.69 cups.

Also called zante currants, corinth raisins, corinthian raisins, dried currants, dried black corinth grapes.

Two sources agree within tolerance. USDA FoodData Central publishes Currants, zante, dried (SR Legacy) at 1 cup = 144 g, implying a density of 0.6087 g/mL. King Arthur's Ingredient Weight Chart lists 'Currants' at 1 cup = 142 g, implying 0.6003 g/mL. The gap between them is 1.41%, well inside any reasonable tolerance, so this entry publishes USDA's figure of 144 g per cup and names both sources. Neither source names a specific filling method.

Zante currants are small dried grapes from the Black Corinth variety of Vitis vinifera, grown historically on the Greek Ionian islands and named for the island of Zakynthos (Zante in Italian). They are related to but distinct from redcurrants, blackcurrants and whitecurrants (Ribes berries), which are unrelated botanically. The confusion in English naming has ancient roots and cannot be resolved by re-labeling, so this entry uses the culinary term 'currants' with the botanical qualifier where needed.

Currants pack noticeably denser than the larger dried fruits published on this site. Dried figs land at 149 g per cup (density 0.6298), dried apricot halves at 130 g per cup (0.5495), and chopped dates at approximately 152 g per cup. Currants at 144 g per cup (0.6087) sit above apricots and slightly below figs. The reason involves both size and shape: individual currants are approximately 5 to 8 mm across, roughly spherical, and firm rather than sticky-collapsible. Small firm spheres pack more efficiently than larger irregular pieces, filling air gaps that fig chunks or apricot halves cannot close. The physical mechanism is the same one that puts small poppy seeds (which land at exactly the same 144 g per cup by coincidence) at higher density than the larger, more irregular whole nuts on this site.

Raisins, published elsewhere on this site in the sugar category rather than the milled category, are the closest analog to currants and belong to the same physical class. Both are small dried grapes, both pack by scoop with predictable fill behavior, and both trade in home baking as interchangeable except at the level of flavor and texture. This entry follows the raisin precedent and places currants in the sugar category as well: their packing behavior aligns with small crystalline or particulate solids rather than with the chunked dried fruits that sit in the milled category. Larger dried fruits like dates, apricots, and figs remain in milled because their piece size and sticky irregularity push them closer to nuts and grains than to grape-sized dried fruit.

Product variants: Zante currants are the standard commercial dried-currant product in the United States, sold under Sun-Maid and similar brands. British and Australian recipes often specify simply 'currants' expecting Zante; European recipes may use dried Corinthian grapes or dried Sultana grapes interchangeably. All trade at essentially the same cup weight per USDA data. Sweetened, oiled, or infused currants sometimes carry added canola oil or sugar syrup to prevent clumping, which slightly increases density; these would earn separate entries if a second authoritative source becomes available.

Currants are placed in the sugar category alongside raisins and other small crystalline or particulate ingredients on this site. The category rule tracks physical packing behavior rather than chemistry or botanical family: small firm particles that pack like granulated sugar sit in the sugar category, whether they are actually sugar (granulated, brown), salt crystals (kosher, table), or small dried fruit (raisins, currants). Larger irregular pieces sit in the milled category. The 10 percent category tolerance applies here, and the 1.41 percent observed gap between sources is comfortably inside it.

No standards body publishes a bulk density for currants. Codex Alimentarius has commodity standards for dried grapes covering moisture content, defect tolerances and sulfur dioxide limits but not physical density. Two independent authoritative sources agree within tolerance, so this entry is held at medium confidence. A third independent source, such as a professional culinary reference or a producer's laboratory measurement, matching within tolerance would move it to high confidence.
