16 years later and I still think of Randy Marsh every time I make it… Master Crème Fraiche Ratio… 1 cup Heavy Cream : 2 Tbsp Culture Stir it up in a clean, sealable jar and let it sit at room temp for 24-48 hours until thick. Pop it in the fridge for 1 more day and boom. Yer done. #cooking #cremefraiche #fermentation
