Ingredients
Granulated sugar is the kind most frequently used in candy-making. To get the best results it should be fine-grained and of the best quality. Confectioner's sugar or powdered sugar is used chiefly to roll or dust candies with.
Almost all confectioners use glucose in their candies, since it helps to keep the sugar from granulating, but, since corn syrup is composed largely of glucose it is advisable for the home candy-maker to use it as it can be readily obtained at the grocery store. A few recipes call for glycerine, and this is quite harmless, and helps to make the candy smooth and creamy. Cream of tartar, vinegar and lemon juice are used to prevent the sugar from graining also.
The butter used in making butter-scotch, fudges and such like candies should be of the very best quality. Never under any circumstances use in candy, stale butter, or substitutes, or butter that is very salty.
