Ah! Now, I’m glad you brought that up. My comments apply only to minced beef sold by the UK supermarkets and Eric theCleric in FR.
Staying with pals in Brittany, shopping in Eric theCleric for minced beef to make spag bol, there was just one choice - ‘boeuf haché’. No ‘fat free’, nor ‘steak mince’, no ‘Angus beef’ mince. Just ‘boeuf haché’. It made a spag bol which tasted of beef like I had never tasted before.
And exactly the same thing when my pal made a chilli con carne with ‘boeuf haché’ from an Eric the Cleric hundreds of kms south, in L’Herault. Beef that tasted of beef!
I set about trying every one of the 4 or 5 variations of minced beef on sale at the 5 principal UK s/mkt chains. Bland, tasteless - all of it.
Probably I would have got better mince at a butcher who minced quality beef - at a premium price. That’s not the point. The point is one can get fab minced beef from Eric theCleric but not from a UK s/mkt, in my experience.
