Potato Starch: Grated, Washed Through a Sieve and Settled

Grate potatoes, wash the pulp through a sieve, and the starch runs out with the water and settles as a white layer. Andrew Ure (1839) describes the works: rasping drums, hair sieves and three settling backs, with starch equal to 17–18 % of the potatoes. Work fast: Ure notes that the quicker it is made, the better the starch. The picture: Huck's revolving sieve for separating starch from potato pulp, engraved in Les merveilles de l'industrie (1873).

Settle three times

Let the milky water settle. Pour the liquor off into a second bucket, then a third; Ure: the finest starch collects in the last. Stir the white layers up in clean water and settle again until the water stands clear.

Dry it

Lift the wet starch out, spread it thin on muslin in a warm, airy place and let it dry. Crumble it to a powder and keep it in a jar. To keep it wet instead, store it under a little water and change the water often.

Limits

The method and yield are Ure's, from works with rasping drums; the hand grater, buckets and quantities are ours.
