People of a certain age – that’s me – might remember the famous error in Robert Carrier’s 1970’s edition of “Great Dishes of the World” which suggested 3 tablespoons of cayenne pepper for the Chilli con Carne, which resulted in a dish that the Maquis de Sade would have been proud to offer. When I saw this recipe for cheese biscuits on Pascale Cumberbatch’s excellent blog – http://extra-relish.com/ – I had a feeling that a similar error had been made. I was wrong. The cayenne/mustard combination just works. My tin of English Mustard powder that had remained in the dark recesses of the store cupboard, still sealed from out arrival in France 10 years ago, has been restored to its former glory in the vanguard of seasonings. I’m cagey about the cayenne – there are still painful memories.
