Ive done SBE's in the past as above.
I can't ref. my times and temps , as that notebook is missing.
more or less : SV 1 - 2 doz eggs , direct from the refrig , time and temp missing here
then rapidly chill , and dry off. place back in the refrig.
in AM : take two eggs out , for example. I had have an old OXO small salad spinner
w the hard white plastic insert that had broken. I add hot tap water to the outer plastic container
again temp not available and the basket , which is set on three plastic jug caps , to keep the basket off the
bottom of the outer container. add the eggs , and microwave for , a set time. the caps keep the eggs in the center of the
hot water. then I go about my AM business : make the coffee , feed the cat , etc etc
make some toast. then crack the SBE's over the hot toast , and scoop out any remaining egg white , if any
presto , two soft boiled eggs on toast in the morning.
the part I liked about this method , is its fool proof , and does not require any timed attention.
the Oxo water bath ended up just heating the precious cooked eggs to serving temp , and did not change
the eggs texture. I might have to try this again. works well
and its mind-less , a key in the AM while waiting for the Coffee.
