We combine our three packs of pasta for dinner – pesto. We tip the dried stuff into a pan, add water and simmer. We try it, looking at each other with disbelief as it hits the tastebuds. ‘It’s pesto, Jim, but not as we know it,’ I say.‘Fascinating,’ says Lou, unsmiling humouring my Star Trek reference, while wincing at the foul food. (And what made me say that? Is there such a thing as a dad-joke vacuum that needs to be filled, even in the wild?)
