I remember when American-style cookies were quite a small player in the UK biscuit market. I also remember the vast majority of them being quite crunchy, and a lot smaller than most you get today. More like the British biscuits. Or, they’d be mostly crunchy, with a lovely, surprising bit of chewiness in the middle. An unexpected bit of indulgence, like you’d eaten it too soon from the oven.
One of my earliest childhood foody memories is visiting my grandmother (who had spent time as a 1950s American housewife) and tucking into her walnut and chocolate chip cookies. They weren’t like anything else I’d tried at the time.
