The problem with new recipes is that many require a pinch of this or a dash of that. But the shops seldom sell ingredients in pinches or dashes. And suppose the the recipe is not a success. You end up with a bag or jar of something you may never use again. What's the answer? Some kind of cookery club where everyone agrees to try the same new recipe on the same weekend and divvy the pinches, dashes and snatches out from a communally purchased jar or bag? Even then there would have to be a lot of club members to avoid bring left with 4/5ths of a bag or jar of whatever.
