The Food Value of Brewer’s Sugar
We do not, of course, use this dark sugar when white sugar is cheap and easily procurable, but during the war we have used it for coffee, cocoa, and tea; and for puddings where colour did not matter. We have used it a good deal in our bakeries for chocolate goods, where colour again does not matter. It is a good, pure sugar, and the colour is the principal drawback.
