Luncheon meat diced into small cubes catches them, for sure, and I dye it red - a bit of Sensas Magic or Robin Red powder - as it looks better, to me at least. I've never tried steak and mince. There's a Fred Taylor book called Tench - there's another by him, Tench Fishing - which I read while reading the local library's entire stock of fishing books aged 13 or 14. I'm pretty sure that some visits to an abattoir are involved. (Maybe Phil's got a line on this?) It's a great book as I recall, with each chapter telling the story of finding, scoping and tackling a different water. The one I envied most was the place that had so many fish they resorted to catching everything that swims until, dozens of fish into the session, they'd find they had a tench on. If only I could find a place like that, I remember thinking.
