I just walked from my office into the kitchen and found this:
Apparently Macarons are being made, and must be monitored.
I guess the problem is problem is that they begin cracking, and this means either you under-whipped or over-whipped, with no way to tell which. This doesn’t seem, to my mind, to be a particularly helpful debugging step, as you don’t know what to change. But I guess at least they won’t come out overly cracked if you monitor them.
This is what happens when Bevin marathon watches the great British baking show while knitting.
