Hi Uni. I wondered about overproving. I did the "bit of dough in a glass of water" trick but as I was in the middle of transplanting a tree the dough had to wait for about 30 mins before I made it in to rolls after it had proved the first time. Perth certainly hasn't been hot, about 20 degrees, cloud and rain so I proved in a 35 degree oven which I usually do. I think I'll have another go when I have some more buttermilk.
