Excerpt from Leavening Agents: Yeast, Leaven, Salt-Rising Fermentation, Baking Powder, Aerated Bread, Milk Powder This volume fills a gap in the literature of baking in this country. The baker kws a good-deal about his ﬂours and also how they are made, but he kws very little about his yeast and less still about his baking powder. He has been well sup plied with literature on the techlogy and chemistry of ﬂour, but much of the data on his aerating agents has either been aimed over his head Or else has been purposely misleading. Aerated bread has been added because of its historical value and because of its possible future. Dry Milk is ather recent important addition to baking materials. Yeast, which is necessarily a technical subject, has been treated in as condensed and simple a manner as possible. The author ackwledges his indebtedness to an anymous friend for the section on the manufacture of yeast. This is the first exact and detailed description Of yeast manufacture in English, and is an important addition to the literature of chemical techlogy. Baking powder is a subject on which the bakers and the public have been misinformed. The water has been so badly stirred up by the baking powder controversy, that the n-technical man has been unable to see beyond the words alum and cream Of tartar. This section has been written without personal bias and the facts have been verified. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
