“ In this case lard, dripping, or good margarine may be used with advantage, and there are also several vegetable fats procurable that answer very well for these purposes; but although they are more economical in price, and some of them are richer where flavour is the first consideration, nothing better than pure butter can be used. So-called cooking butter is in too many instances nothing but margarine, but there should be no compunction in buying margarine under its right name, and paying a corresponding low figure for it. ”
