Mustard leaves are peppery brassica greens used in Indian, Chinese and Southern US cooking. They are rich in vitamins A, C and K, with folate, calcium and glucosinolate compounds linked to brassica health benefits.
Boil briefly in a small amount of water to keep more vitamin C and glucosinolates; long cooking softens flavour and reduces these compounds.

* % 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.
