Thanks, cschaaf, but that's where I started. Actually, I originally started with the French Laundry technique of 142F for 50 minutes. PERFECT eggs, but who wants to wait over an hour for breakfast?? So, MacKenzie and I have been doing various trials to find good poached eggs for breakfast in a reasonable amount of time (15 minutes or less). As noted in the "calculator" the whites and yolks cook completely differently. It's a delicate balancing act to get runny yolks with firm whites. And by "firm whites," I mean ones you can eat with a fork and not require a spoon. MacKenzie is the one that came up with the boiling water bath to tighten up the whites without overcooking the yolks. Not that big of a complication - just put a bowl of water in the microwave a few minutes before the eggs are finished in the SV to set up the boiling water bath. A quick dunk in the hot tub and into the cold water bath to arrest the cooking and you're done. It was just a matter of figuring out the various times in each bath. Plus, the added variable of MacKenzie letting her eggs come up to room temperature and me taking mine straight out of the fridge.
