Sattu

Cicer arietinum (roasted) · Sattu · chana sattu · roasted gram flour

A flour already cooked, waiting only for water.

What it is

Sattu is the flour of roasted Bengal gram, sometimes cut with roasted barley. The roasting is the whole point: the grain is cooked before it is milled, so the flour is edible as it stands and needs no heat at all. It is pale fawn, dry, faintly sweet, and smells of toasted nuts. Stirred into water it thickens without lumps.

Where it comes from

It belongs to Bihar, eastern Uttar Pradesh and Jharkhand, where it has fed field labour and mill work for as long as anyone records — cheap, keeping indefinitely without refrigeration, and needing no fuel to prepare. Bihar named it the state's official health food in 2022, which formalised something the plain never doubted.

What it's called

Sattu · satu. Chana sattu is the gram version and the default; jau sattu is barley. Do not confuse it with besan, which is raw gram flour and behaves completely differently.

In the kitchen

Two directions. Savoury: whisked into cold water with black salt, roasted cumin, lemon and green chilli as a drink; or bound with mustard oil, ajwain and pickle masala and stuffed into paratha and litti. Sweet: stirred into water or milk with jaggery or sugar. It thickens as it stands, so mix and drink.

What we know about the claims

The protein content is real — around twenty grams per hundred, with substantial fibre and a low glycaemic response. The traditional claim that it cools the body in summer is a claim about how it is eaten, not a measurable property, though a cold high-fibre drink taken before work in the heat is not a bad idea on any account.

Choosing and buying

Sold as sattu or roasted gram flour in South Asian grocers and increasingly online. Check the label says roasted; besan is not a substitute and will taste raw and chalky. It keeps for months in an airtight jar, but the roasted aroma fades — buy in quantities you will use.
