Final answer:
Multiply the quantity of instant yeast by 3 to obtain the equivalent amount of compressed fresh yeast.
Step-by-step explanation:
When converting between instant yeast and compressed fresh yeast, a common conversion factor is to use a ratio of 3:1. This means that for every unit of instant yeast required, you can substitute it with three times that amount in compressed fresh yeast. The reason for this conversion lies in the differences in moisture content between the two types of yeast. Instant yeast has lower moisture content, so a smaller amount is needed compared to compressed fresh yeast.
This conversion is particularly useful in recipes that specify one type of yeast but you have the other on hand. By using this 3:1 ratio, you can achieve consistent results in your baking while accommodating the differences in yeast types.
