for me
it comes down to the ease
of making certain things , well ahead
and close to perfectly done
that I can then use later .
eggs , pressure steamed , potatoes , for a salad later
again , steamed .
however , the finest mashed potatoes ive ever done
are pressure steamed , then added back to the pot
after the hot water is discarded
and then mixed in that pot. , in the usual finishing fashion
after that. haven't made those in a while
as with all things , doesn't do every thing well
just a few things
Like the having those items ,
to work with , on purpose
later.
