I spent over £20 on a 30 days matured taste the difference beef joint for xmas day from sainsburys. My guests in their 80s had not eaten outside their home since pre covid so i wanted it to be nice and they preferred this to turkey.
There was no mention of any cooking instructions on the outer packaging. When i opened it on xmas day i found it had to be cooked in liquid and was not the roast I expected. Googling silverside i can see that all silverside is recommended to be cooked this way otherwise it is tough but i had no idea. All the silverside joints were mixed in the cabinet with rump joints as each was individually priced. I never even considered there would be a difference and as it was such an expensive joint I just presumed it was a a traditional roast. It was labelled "British beef silverside joint".
AIBU to think Sainsburys should have explained this on the packaging as surely I am not the only person who doesnt know this. I wouldnt normally have beef except for the visitors.
