Mixed grain Rolls from a cold start.

These rolls, based on the No Fuss recipe, but using a mixture of whole grain flours.
They were placed in a cold oven for 15 mins at 160 oC and then 15 min at 200 oC. The first rise was done in the TMX bowl, and as it was very cold here today I proved it in the oven warmed to 70oC.
