Smooth prepared mustard (such as Dijon or smooth English mustard) is made from finely ground brown or white mustard seeds combined with vinegar, water, and salt, producing a smooth, pungent condiment. It is very low in calories and contains glucosinolates and isothiocyanates from mustard seeds, which have antioxidant and potential anti-inflammatory properties. It can be moderately to highly salty depending on the variety.
Use smooth mustard as a low-calorie flavour booster in dressings, marinades, and sauces — a teaspoon in a salad dressing adds pungency without significant calories. Store in the fridge after opening to preserve flavour.

* % 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.
