apparently, bread machine yeast is instant yeast.
here's part of an FAQ I found
here:
Quote:
Can Active Dry Yeast be used in RapidRise recipes?
Yes, but with limitations. The Active Dry has larger granules and it is necessary to dissolve completely for the yeast to work. Therefore, Active Dry works best if dissolved in warm water (100° to 110°F). To use the electric mixer method, combine yeast with 1/4 to 1/3 of the flour and other dry ingredients.
What is the difference between Instant Yeast, Bread Machine Yeast and RapidRise Yeast?
Mainly names, but these are all the same yeast! Use interchangeably
What is the difference between fast-rising yeast (RapidRise/Bread Machine Yeast) and Active Dry Yeast?
RapidRise and Bread Machine Yeast are different strains than Active Dry Yeast. RapidRise and Bread Machine Yeast are grown with a higher level of nutrients and are dried to lower moisture content. The particle size of RapidRise and Bread Machine Yeast are finely granulated to allow complete hydration of the yeast cells during the mixing process. The Active Dry Yeast larger particle size should be dissolved in water to achieve complete hydration prior to adding to the mixer. In addition, RapidRise and Bread Machine Yeast contain ascorbic acid resulting in increased loaf volumes.
Can Active Dry Yeast be used in bread machines?
Bread Machine Yeast is a fast-rising yeast specially formulated for bread machines. It is finely granulated to hydrate easily when combined with the flour. Ascorbic acid (vitamin C) is added to promote good loaf volume and structure. Active Dry Yeast may be used but may not yield optimal results.
