There I was, thinking Max's questions were easy peasy when he threw me this one: 'Does peppercorns come from a tree, Mummy?' This was as he was going through the kitchen cupboards and asking me to identify the contents. I had to turn to wikipedia to clarify that pepper actually comes from a flowering vine, the peppercorn is the single seed inside the blueberry-like fruit. Who'd have known? His next question? Well of course, it was 'Mummy, does peppercorns say 'yum, yum, yum?'
