Black treacle is a thick, dark, strongly flavoured syrup that is a by-product of sugar refining, similar to blackstrap molasses but typically slightly less bitter and with a more complex flavour. It retains significant minerals including iron (~5mg/100g), calcium, magnesium, and potassium from the molasses, making it nutritionally far superior to refined sugar. It is used in British baking (treacle tart, gingerbread, sticky toffee pudding) and as a traditional iron-rich food.
Black treacle has a very strong, slightly bitter flavour — use in conjunction with golden syrup (typically a 1:3 ratio in British recipes) to balance intensity. It blends easily into batters when gently warmed. A tablespoon provides around 1mg iron.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
