Today we find out how some of Cambridge’s local independents began, by accident or design. We celebrate the tomato with an essay from Laura Donohue and ideas for cooking them from local chefs Tristan Welch, Sam Carter, Rosie Sykes and Jamie Mountford. Also, Steve Thompson goes foraging and has ideas for fermenting, including honey with blackberries; we catch up on news from Vanderlyle with Alex Rushmer and Lawrence Butler. Presented by Matt Bentman, Alan Alder and Sue Bailey.
