To make a poolish preferment that is 100% hydrated and uses 33% of total flour, how much of each ingredient is needed if the totals are 15# bread flour and 10# water?

To make a poolish preferment that is 100% hydrated and uses 33% of total flour, how much of each ingredient is needed if the totals are 15# bread flour and 10# water?

• A. 5# Flour, 5# Water
• B. 7.5# Flour, 7.5# Water
• C. 10# Flour, 10# Water
• D. 3# Flour, 3# Water

Answer: (A)

To produce a poolish preferment that is 100% hydrated, you need equal weights of flour and water. In this scenario, the target is to use 33% of the total amount of flour in the final dough for the poolish. Starting with the total amounts of flour and water, 15 pounds of bread flour means that 33% used for the poolish is calculated as follows: 0.33 x 15# = 4.95#, which can be rounded to 5# for simplicity. Since the poolish is 100% hydrated, if you use 5# of flour for the poolish, you will need the same amount of water, which is also 5#. Thus, for this particular case, using 5 pounds each of flour and water aligns with the requirements for creating a balanced poolish, ensuring that it has the correct hydration level and uses the specified portion of the total flour. This method is a common practice in baking, especially in artisan bread making, to enhance flavor and fermentation.
