Picked up a couple of Beyond Burgers from Tesco today. Weirdly just in my local Tesco extra (no I don't live in Kensington). Cost a bloody fortune (£5 for 2), but thought I'd give them a try. And tbh they weren't bad... Texture was decent, flavour ok. Probably should have taken some pics, since I'm unlikely to buy them again for while (due to cost), but hey. For context I eat meat, but am intrigued by things that might actually be effective in limiting consumption... This was the closest I've come to something that could actually substitute a burger patty (as opposed to being a kind of burger equivalent).
Think I might give the Meatless Farm burgers a try next, they being half the price. They also do mince and sausages (though tbh I'm quite a fan of Linda McCartney red onion for sausage-adjacent foodstuffs). I think I might also have a go with some marinades, and using them in other dishes.
But yeah, overall a worthwhile experiment... Hopefully get a chance to try them on a barbecue before the cold sets in.
