Fresh cow-whey ricotta from the summer alpine dairies is kneaded with salt, pepper and a little caraway, then left in wooden tubs in cool rooms. Over 45–60 days it sours slowly until, the ERSA sheet says, it is acid enough to keep, giving a white, pungent spread eaten from autumn to spring.

Fresh cow-whey ricotta from the summer alpine dairies is kneaded with salt, pepper and a little caraway, then left in wooden tubs in cool rooms. Over 45–60 days it sours slowly until, the ERSA sheet says, it is acid enough to keep, giving a white, pungent spread eaten from autumn to spring. Made in 4 steps over 45 days – 2 months. The longest step, sour slowly in tubs, takes 45 days – 2 months (ERSA 2018).
The ERSA sheet says the souring is taken to the point where the cream is microbially stable; it is then kept in a cold room. The sheet gives no pH or test result, so that is its claim, not a measured result.
