Pierre Blot, Hand-Book of Practical Cookery…
“ We think that the only difficulty, if difficulty there be, is in the use of the yeast, the making of the same, and the baking. Chemical processes for rising will never equal the processes of nature and time. Many bakers do not use the yeast properly, their bread being sour or musty; some sweeten their bread, to disguise an inferior quality of flour, or as an antidote to sourness or mustiness. ”
