Mix together flour, butter and cheese until the mixture forms a ball. Place the mixture on a piece of plastic wrap and shape into a log about 4cm in diameter. Refrigerate until firm.
Place slices on ungreased oven trays, leaving several centimeters space between biscuits.
Sprinkle with a little salt, and bake in a moderate oven for about 15 minutes or until lightly browned. Cool on trays. Serve with cheese, particularly good blue cheese. Makes about 30 biscuits which will keep up to 5 days in an airtight container.
