Interesting. A couple questions on the make details.
Do you raise the temperature to 38 during the 40 minute stir, or stir then raise to 38? I would think the raising from 32 to 38 should take about 30 minutes, making it a 40 minute stir, 30 minute stir and rise, and 30 minute stir and maintain, correct?
Also, given that it's waxed, the humidity shouldn't matter.
Finally, what was the diameter of your mould?
I want to make notes on this one as it looks like a nice one to try out and I would like to get it right. Thanks.
