Sandwiches, for all their lunchtime humility, are one of the great constants of modern eating. They are democratic, portable and reassuringly familiar – yet, as anyone who has stared bleakly into a fridge at midday will attest, they are also remarkably easy to get wrong.
The same fillings, the same bread, the same faint sense of culinary deja vu. Little wonder that nearly 90 per cent of us eat sandwiches at least once a week, while a sizeable minority power through them with near-daily devotion. More telling, though, is that almost two-thirds admit they are bored of their usual choices.
