Single-conversion pages for instant yeast
Working with instant yeast
Instant Yeast sits in the leaveners, salt & spices group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. Also sold as rapid-rise or bread machine yeast. Use about 25% less than active dry by weight for the same rise time.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
Frequently asked questions
How many grams are in a cup of instant yeast?
