Mustard greens
sarson ka saag
The green that makes the Punjab's winter.
What it is
Mustard greens are the broad, peppery leaves of the mustard plant — assertive and faintly bitter raw, mellowing to a deep, savoury green when cooked down long and slow. They are the heart of sarson ka saag, the north's great winter greens dish.
Where it comes from
They belong to the winter cooking of the northern plains, above all the Punjab, where sarson ka saag eaten with cornbread (makki di roti) is the defining seasonal meal. Bathua and spinach are often cooked in alongside them to round the sharpness.
What it's called
Mustard greens · sarson (Hindi) · sarson ka saag as the dish. Leaves of the mustard plant (Brassica).
In the kitchen
Cooked down for a long time with ginger, garlic, chilli and a little cornmeal to thicken, into the slow, rustic sarson ka saag — finished with butter or ghee and eaten with makki di roti. The long cooking is what tames the pepperiness into depth. Not a quick green.
What we know about the claims
Mustard greens are rich in vitamins and minerals — a genuinely wholesome winter vegetable. No caution beyond thorough washing.
Choosing and buying
Fresh mustard greens appear seasonally in South Asian grocers (UK and US) in winter; tinned and frozen sarson saag exists as a shortcut. Choose fresh, unwilted leaves in season.
