A copper pan, a bank statement, and a recipe.
In 1991, Jean Campbell wrote her grandmother's fudge recipe on the back of a Royal Bank of Scotland statement, set up a single copper pan on the cottage stove, and made twelve blocks to sell at the Biggar farmers' market.
Eleven sold by lunchtime. The twelfth was eaten by Jean's husband Hamish, who insists to this day he was "just quality checking."
Three decades later, the copper pan is the same. The kitchen is the same. The market stall is gone, but the fudge still leaves Hawkshaw Cottage by van once a week.
