SW book states that 1tsp (5ml spoon) sugar is 1 syn, and that sugar cubes are only 0.5 each. A sugar cube is 4g and a teaspoon holds 4.5g so why the variation of syns? I want to be sure I am synning my sugar cubes correctly and that its not a misprint in the sw book. Am I right to be synning 0.5 for sugar cubes?
