Further update: today my wife ate one and said, unprompted, “These are good.” She is not usually given to such outbursts of enthusiasm :-). I asked whether she likes them better than other kinds of biscuit I make (which I think are particularly good, else I wouldn’t bother making them) and she said maybe. She specifically disagreed with my judgement that they’re a bit boring. So, one data point in favour of the hypothesis that for some people these are unusually tasty biscuits.
