I'd always used a local butchers (I passed there daily, while going to the post office) until he retired some years ago, then sadly soon after passed away, top bloke, well missed.
Anyway, after he retired I would but meat from the supermarket, Lidl specifically, and I was surprised at the quality, I was sure it must have improved over the years because I had it in my mind that it wasn't very good.
These days I have more time on my hands so have been shopping on our local market, today I threw away 2 chicken thighs that were stinking, I bought 4 on Thursday and cooked 2, was planing to use the others today. Is that normal?
I can think of other situations where i've thrown meat away, one conclusion I can draw is that whatever else, supermarket meat is a lot cheaper and keeps for longer.
