As humans, we’ve gone to great lengths to overcome legumes‘ natural defences. We have the tenacity of our forebears to thank every time we fill a bowl with chili or swipe refried beans with a tortilla. Take lupins, which require boiling and washing for a week while frequently changing the water to make them palatable. Even then, they don’t soften, but no need to worry. Do as the Italians do and pop them like olives as a bar snack.
