How to make butterscotch bars:
This makes a fairly brittle, buttery flavored toffee, very much like the traditional Scottish butterscotch. See Cooking with Sugar for information on the tricky process of boiling sugar.


1 cup granulated sugar
1/4 pint water
pinch of cream of tartar
6 tablespoons butter, cut into small pieces
(see measure conversions for more information)


- In a large heavy bottomed saucepan, dissolve the sugar in the water.
- Add a cream of tartar and boil to 138oC (280oF).
- Remove from heat and add the butter gradually.
- Boil to 149oC (300oF).
- Remove from the heat and pour into a suitable buttered tin.
- When the butterscotch starts to set mark into bars with a buttered knife.
