Leave to rise in a warm, draught-free place for 30 minutes.
Cover with cling-film and leave in a warm, draught-free place for an hour until doubled in size.
3 When the milk reaches this temperature, stir in the live yoghurt, cover with a plate, a lid or clingfilm and place in a warm, draught-free area.
French nomenclature divides horse breeds into three groups: warm-blooded, draught horses and ponies.
The populations considered in the present study can be classified into four more or less differentiated clusters: warm-blooded, draught, Nordic and pony breeds.
According to genetic relationships, multivariate and structure analyses, breeds could be classified into four genetic differentiated groups: warm-blooded, draught, Nordic and pony breeds.
The enclosed conditions (to reduce the frequency of thread breakage, cotton mills were usually very warm and as draught-free as possible) and close contact within mills and factories allowed contagious diseases such as typhus and smallpox to spread rapidly.
For K = 2, there was a clear separation between draught and warm-blooded horses, with other populations showing intermediate results.
These 39 populations comprised 31 recognised breeds (including 13 warm-blooded breeds, nine draught breeds, and nine pony breeds), the primitive Przewalski horse (used as an outgroup), and seven populations originating from the splitting of two recognised breeds, namely the Anglo-Arab (AA) and Selle Français (SF) breeds (divided into four and three groups, respectively).
Closing curtains or blinds after dark also traps in the warm air and prevents draughts.
As K increases to 4 and 5, the five clusters were constituted of Nordic/primitive breeds, draught horses, ponies, warm-blooded populations close to the AR breed and warm-blooded populations close to the PS breed.
