Yes. If the recipe calls for bread machine yeast then you should use it. If you exclude the yeast then the bread will have difficulty rising. Bread machine yeast is a rapid rising yeast designed to work well with bread machines. This helps to save time when making bread and makes the bread making process even easier with a bread machine (because there isn’t a separate yeast activation phase). All you have to do is add the bread machine yeast to the other recipe ingredients and turn the bread machine on.
