Turep starch (Ainu lily-bulb starch)
Starch released from giant woodland lily bulbs by pounding, washed out in water, settled and dried: the refined fraction of an Ainu process that also yields fermented cakes from the residue.
Modern adaptation
Бородинский хлеб · Borodinsk-ish
A dark rye sourdough with coriander and roasted barley-malt scald, based on Lily McCann's measured Borodinsk-ish home formula.

Borodinsky bread is associated with Russian rye baking. Lily McCann's article on its history says its origin stories are competing legends and reports that the earliest written recipe she found dated to 1933. She also describes the ingredient proportions and scalding method of Soviet standard GOST 5309-50, while noting that later rules were less prescriptive.
The recipe here is McCann's own home adaptation, published by the Real Bread Campaign as “Borodinsk-ish.” It uses a rye sourdough, roasted barley-malt scald, coriander, molasses and a long staged fermentation. The method is useful as one measured version; it does not establish a universal formula or current compliance with a historical standard.
The source lists 30 g malt flour, 90 g rye flour and 300 g water for the scald (420 g total), then calls for 370 g of scald in the pre-ferment. It does not account for the remaining roughly 50 g; the formula above keeps the published source quantities and notes the gap rather than adjusting them.
Lily McCann describes Borodinsky as a well-known Russian black rye bread and says its origin legends are not established. Her article reports that the first recipe she found was dated 1933 and discusses the Soviet GOST 5309-50 formula. The selected home recipe is titled “Borodinsk-ish” and should not be treated as a canonical or current standards-compliant formula.
Yield 1 loaf in a 1 kg tin · Scaling: source batch only
Rye and wheat flours are uncooked before the loaf is baked; do not taste the raw dough.
Hazard sourceDo not taste the raw dough; bake the loaf as directed and wash hands, bowls, utensils and work surfaces after handling flour or dough.
Control sourceThe source gives a visual colour and pan-release cue but no measured internal-temperature endpoint. Do not infer a validated doneness temperature.
The recipe author presents this home adaptation as inspired by classic Russian Borodinsky rye bread; the source does not identify a narrower regional origin for this formula.

Lily McCann's Borodinsk-ishProvides a measured two-day home recipe with rye starter, roasted barley-malt scald, coriander, a 4-hour pre-ferment, 2–3-hour final fermentation and 2–3-hour tin proof.
Specifies a 1 kg tin, soft rye-heavy dough shaped using oiled clingfilm, 200°C fan oven for 40–45 minutes, cooling and a minimum 24-hour setting rest.
Describes the recipe as “Borodinsk-ish,” a home approximation inspired by Russian Borodinsky bread, not a universal or canonical formula.
