I could not find @Anna N ' comment on Costco mechanically tenderizing its meat.
as My FCO was going well , even though St.P's day's S&S point CB's will have an impact ...
( a tasty one ! )
I had planned to get a gift certificate from time to time in the future to get various Prime Cuts there as a well deserved treat
from time to time.
Id SV the meat them deal with its consumption in various ways later.
I was alarmed that C' does this with tis meat. it precludes SV
So I called a Costco 20 min away from me , very close to :
https://www.shakeshack.com which has the best SmkeShake burger ....
I spoke to one of the butcher's and they were very nice and straight forward on this :
yes all meat is mechanically tenderized. they clean the system frequently etc they also were very familiar with SV
and understand their routine meat in the counter might not be best for SV they said this themselves.
but as something happened in Canada , which I haven't looked into
they said they would be happy to not do this to any customer as asked on the spot. you even get to see them cut up your stuff right there;.
they said they were happy to do this , as some customers asked about it.
so fully ijmformed you can get around this at least at the Costco I call w is in Dedham MA.
that was close Id say.
