My mum made these biscuits, and they are delicious. I like them with the cream cheese filling from recipe 24672, and topped with strawberries and the whipped cream from recipe 410125 (filling, no mint). I do not recommend substituting margarine for butter, but it can be done in a pinch. I use low fat sour cream. I sometimes form 8 rough balls, flattened instead of rolling the dough and cutting rounds.
