The packaging of the salad I bought in my local supermarket describes the contents as "peppery wild rocket and vibrant baby-leaf red chard". I know what "peppery" tastes like; but Mr Sainsbury, please explain how "vibrant" tastes. The Concise Oxford, 6th edition, defines vibrant as: "Vibrating; thrilling with (action etc.); responding readily to emotions etc.; (of sound) resonant." The salad is quite nice, and I'm likely to buy it again, but I cannot say I found the red chard thrilling or resonant, synaesthete though I am. Didn't get too much of a response to my emotions either.
While you're at it, Mr Sainsbury, please tell me why you consider pea shoots an acceptable salad ingredient. They may be green and non-poisonous but that doesn't make them edible. Don't you know that most green stuff is not in fact edible? Grass, tree leaves, hedges, weeds, brussels sprouts - we don't like to eat them.
All the same, I love the man-made miracle of supermarkets. For a pound or so - the equivalent of about three minutes of work - I can buy a fresh, washed, bug-free pack of salad. How much would it have cost me to grow that, harvest it, prepare it, and have it ready just when I wanted it?
