Set a timer for twenty minutes and don't add it to anything until it has a good head on it (like beer) and smells yeasty. I was apparently not getting my water hot enough. (I now do about a minute in the microwave.) Mine usually takes about ten minutes to 'bloom'. I've got the touch! I am now making some darned fine brioche and babka!
DP. I also use a thermometer but have success between 100-110 F (after whisking the yeast with the water cover with tea towel and let sit for 5-10 minutes)
