Flour Ball Gruel
Tie loosely into a half-yard square of thick white cotton cloth one pint of sifted bread flour, place it in a pan of boiling water and let it boil for six or eight hours. The flour will come out a solid chalky ball. To make the gruel, grate from this ball two tablespoonfuls and stir into boiling water with a pinch of salt. Cook for twenty minutes and then add a little cream or milk.
A sick-room staple built on a technique that has vanished entirely: flour boiled for hours inside a cloth until it sets into a dry, gratable mass. The gruel itself takes minutes; the ball is a keeping preparation made in advance.
- The cloth and the tieA half-yard square is about 18 inches of thick white cotton, as the recipe specifies. Tie it loosely, as instructed; the likely reason is that the flour swells as the outer layer gelatinizes, and a tight bundle risks splitting.
- Why it takes six hoursThe outside of the flour pastes into a near-waterproof shell within minutes, after which the interior is effectively cooking in trapped steam. Long boiling was believed to break the starch down into more digestible form, which is the stated point of the exercise; shortening it leaves raw flour in the middle.
- Keep the pot topped upThe bundle must stay submerged for the whole time. Add boiling water as it evaporates, and set a plate or trivet under the ball so it does not scorch on the bottom of the pan.
- Finishing the ballThe recipe says it comes out a solid chalky ball. The wet outer skin of paste is not part of the gratable interior; some cooks peeled it away and let the ball dry before grating, though this recipe does not say so.
- StorageThis is where the recipe assumes a cool larder and daily use. A damp ball moulds readily, so keep it dry and airy and inspect it before each grating; discard at any sign of musty smell or discoloration.
- Proportions for the gruelThe recipe fixes two tablespoons of gratings but not the water; less water gives something closer to a porridge, more a thin pourable gruel. Whisk the gratings in slowly or they clump.
- Twenty minutes is not paddingEven dextrinized flour needs sustained simmering with liquid to thicken smoothly and lose any pasty taste. Add the cream or milk at the end, off the boil, so it does not catch.
- YieldOne pint of flour makes a ball that yields a good many two-tablespoon portions, so a single ball was clearly meant to serve an invalid over some days.
Flour balls belong to the nineteenth-century sick-room, where the governing theory was that starch had to be broken down before a weakened stomach could manage it. Long boiling in a cloth was the domestic way to do that, and the same preparation appears in British and American household manuals under names like "boiled flour" and "flour ball," recommended for invalids, convalescents and often for infants who could not tolerate plain milk. Its place among foods for invalids reflects the period's confidence that cookery was a branch of nursing: a housekeeper was expected to produce beef tea, barley water, arrowroot and gruel as a matter of course. Commercial precooked and dextrinized cereal foods eventually did the same job from a tin, and the technique fell out of home kitchens.
