About Molasses (Treacle)

The dark, intensely flavoured syrup remaining after sugar crystals are extracted from cane juice — the defining flavour in gingerbread, treacle tart, and Christmas pudding.

Why the Weight Per Cup Varies

Weighs 330g per cup, slightly less than honey/golden syrup due to a different sugar concentration and water content. Best measured by weight, since it clings stubbornly to volume measures.

Names in Different Countries

"Molasses" (US/Canada) = "black treacle" (UK). Distinct from "blackstrap" molasses, which is much more bitter and concentrated.

Common Recipe Uses

Gingerbread, parkin, Christmas pudding, dark fruit cake, baked beans.

Substitutions

No true substitute for its intensity; dark brown sugar contains a little molasses and can work in small amounts.
