Penicillium Roqueforti (PS)
Penicillium Roqueforti (PS) has a medium-fast growth rate, with a mild blue taste and blue-green color. This mold powder can also be used in conjunction with Penicillium Candidum (HP6).
Amounts used will vary depending on the type of cheese being made.
Adding Directly to Milk
Add 1/16 - 1/8 tsp penicillium roqueforti to 1/4 cup milk, let rest 30 minutes. This allows the mold powder to re-hydrate.
Add milk and re-hydrated penicillium roqueforti to 2-4 gallons of milk, at the same time you add culture.
Adding to Finished Curds
Add 1/16 - 1/8 tsp penicillium roqueforti to 1 quart sterile, cool water, let rest 10 hours. This allows the mold powder to re-hydrate.
Place 1/3 of the curd into a cheese mold, sprinkle sparsely with re-hydrated penicillium roqueforti solution. Add another 1/3 of the curd, sprinkle again, finish with the final 1/3 of the curd, sprinkle once more.
The re-hydrated penicillium roqueforti solution can be stored in a refrigerator for up to 3 days.
