So, a repeat of yesterday - blanched for 90 seconds, then 45 minutes at 63.5C.
And, strangely, very similar results 
My wife loves it at this level.
It’s one of the great things about sous vide, the metronomic repeatability of it, it removes a lot of variables. (Which is one reason so many restaurants use it, of course.)
OTOH, I think blanching it for that long is too much, so on Monday (probably, due to fasting) I’ll try it with about 75 seconds blanching then 45 mins at 63.5C.
I also put another egg in with this morning’s batch that was also blanched for 90 seconds, but I’m leaving it in the SV until lunchtime, to see how much - if any - difference it makes if I cook it for four hours rather than 45 minutes.
Also worth noting, if the eggs crack when you’re blanching them, they’re fine to sous vide. At least one of the ones in the pic above had cracked, along with one from yesterday’s eeggsperiments.
