Soured milk as the centre of a food culture: eaten plain, drunk as ayran, cooled into tarator, stirred into soups and baked into banitsa. Fermented by Lactobacillus delbrueckii subsp. bulgaricus with Streptococcus thermophilus โ the organism was named for where it was first isolated, which is not the same as a claim that Bulgaria invented yoghurt.
Lactobacillus delbrueckii subsp. bulgaricus was named for Bulgaria because Stamen Grigorov first identified it in Bulgarian soured milk in 1905. That is a documented fact about a naming. It is not evidence that yoghurt originated in Bulgaria, and this dataset makes no such claim.documented
The popular claim that Bulgaria invented yoghurt, or that Thracians made it, is recorded as a folk claim. Soured milk is documented across a very wide pastoral world long before any of the modern national cuisines existed.folk claim
