How is sattu made? The roast-and-grind method at home

The FSSAI standard for chana sattu compresses the whole method into one sentence: sattu is obtained from gram (Cicer arietinum) that is clean, washed, dried and sound, ground only after it has been roasted. The same standard fixes the finished flour: moisture capped at 8 percent, the whole batch fine enough to pass 35 mesh, a uniform colour, and the characteristic roasted taste, smell and flavour. At home the identical logic runs in four moves — roast the clean gram through, let it cool completely, grind it fine, sieve it. Everything below is detail on those four moves.

Chana sattu, the roasted gram flour this page covers, is made of one ingredient: gram (Cicer arietinum), the pulse sold in Indian shops as chana, roasted and then ground. The standard's own wording is "grains of gram", and it allows no extraneous matter and no adulterant. The order of the two steps is what makes the food: grind dehusked gram without roasting and you get besan; roast the gram first and you get sattu. The pulse in between the two — roasted but not yet ground — is a familiar snack in its own right; the dietary guidelines list roasted chickpeas among nutritious snack options, and sattu is that same gram, milled. For the flour's names, nutrition and uses, the sattu hub is the index.

1. Pick the gram. Start with 250 g of Bengal gram (chana), whole or split. Spread it on a plate and pick out stones, discoloured grains and dust; the standard's first words — clean and sound grains — are the same job.
2. Wash and dry, if you wash. The standard says washed and dried. If the gram is dusty, rinse it, drain thoroughly and spread it out on a cloth to dry completely; wet gram steams in the pan instead of roasting.
3. Roast on a low flame. Heat a heavy pan or kadhai, add the gram in a single layer and stir without stopping, 15 to 20 minutes, until every grain is evenly golden-brown. Taste one: it should snap and taste toasted right through, with no raw centre.
4. Cool completely. Spread the roasted gram on a wide plate for 30 to 60 minutes. Warm gram clumps in the grinder and steams the flour, so wait until it feels fully cool.
5. Grind in small batches. Fill a dry mixer jar no more than half, pulse in short bursts and shake between bursts. Running the mixer continuously heats the flour and pastes it against the jar.
6. Sieve. Pass the flour through a fine sieve — the finer the sieve, the closer you get to the standard's 35-mesh requirement — and re-grind whatever stays behind. Sieve once more at the end.
7. Cool and jar. Let the fresh flour cool, then store it in an airtight jar.

A home mixer-grinder handles small batches well in short pulses; for a large batch, a mill (chakki) at the local atta shop grinds the lot at once — ask for a fine grind, and sieve it again at home either way. The fineness that counts is printed in the standard: commercial chana sattu must pass a 35-mesh sieve in full, which is a fine, almost powdery flour. A coarser home grind is still sattu and still roasts the same way; the sieve decides how smooth the drink ends up, not whether the flour is sattu.

• High flame. Scorched outside, raw inside. Keep the flame low and keep the gram moving; the roast takes the full 15 to 20 minutes and cannot be hurried.
• Grinding warm. The moment the gram is only warm, the flour clumps and the jar steams. Cool it completely first — the half hour on the plate is part of the recipe.
• Skipping the sieve. Unsifted flour drinks gritty; the sieve is also how you catch the odd unhulled piece.
• Roasting a mix in one pan. Different grains finish at different times; roast any add-on grain on its own under a low flame and blend the flours afterwards.
• A damp spoon or a damp jar. The standard caps sattu's moisture at 8 percent; a wet spoon starts lumps, and the guidelines say to protect stored grains from moisture. Dip with a dry spoon only.
• Buying besan thinking it is sattu. Read the pack name: the standard calls the roasted flour chana sattu, and it should be of uniform colour with the characteristic roasted taste, smell and flavour.

The numbers below are kitchen timings for 250 g of gram in an ordinary home kitchen; a heavier pan or a crowded pan shifts them a little either way.

These are kitchen timings. The fixed requirements are the standard's: clean, washed, dried gram, moisture not more than 8 percent, and a grind fine enough to pass 35 mesh.

Storage follows the same lines the guidelines give for dried grains: store them dry and in airtight containers, which protects them from moisture, and dry the gram well before it goes in. For whole gram kept in bulk, there is a known pest to watch for — the pulse beetle, which glues its eggs to the grain surface; the grub then develops inside the seed and the adult cuts its way out through a round exit hole. Keeping the gram dry and sealed is the first line against it; the guidelines also mention that dried neem leaves in the bin are a traditional practice known to prevent some infestations, never a replacement for a sealed container. Sattu itself is a dry flour and keeps well in an airtight jar on a cool, dry shelf; smell it before use.

What is sattu made of?

Chana sattu is gram (Cicer arietinum), roasted and then ground. The FSSAI standard describes it as sound gram — cleaned, washed and dried — that is roasted before grinding, with nothing else added, so plain sattu is a one-ingredient flour.

How is sattu made?

The gram is roasted on a low flame until it is toasted through, cooled completely, ground to a powder and sieved. Roasting before grinding is what makes it sattu; the same gram ground raw is besan.

What is sattu made up of?

Chana sattu is one ingredient: roasted Bengal gram, ground fine. The standard allows nothing extraneous, and the finished flour should carry the characteristic roasted taste and smell of the gram itself. If a second grain is wanted, roast it separately and blend the flours after grinding.

How to make sattu?

Pick clean gram, wash and dry it if needed, roast it in a heavy pan on a low flame with constant stirring for 15 to 20 minutes, cool it fully, then grind in short pulses and sieve, re-grinding the coarse bits. Jar it dry and airtight.

What is sattu flour?

Roasted gram flour: the milled form of the roasted chana that is also eaten whole as a snack. Because the roasting comes before the grinding, the flour goes into drinks like the sattu drink and into doughs; besan is ground from dehusked gram with no roasting.
