Whatever happened to haricot beans? I have used the dried beans in soups, stews and many different bean dishes all my life, but they have suddenly disappeared from supermarket shelves. Waitrose and Morrisons list them as available online, but do not stock them in store – at least, not where I live. Have they been forced out by more exotic-sounding, fashionable pulses? They are a really useful ingredient.
