No. 3667 — Restoring Slightly Sour Cream
English historical translation of Molokhovets recipe No. 3667 from the 1901 Russian cookbook, retaining original methods and measures.
When cream has begun to turn sour, the author recommends mixing in 1 small level spoonful baking soda per teacup cream before bringing it to a boil, claiming that it then will not curdle.
Historical editorial note: Soda may alter acidity but does not make spoiled dairy safe. This is a historical culinary claim.
Original source: Read Russian recipe No. 3667. Historical quantities and terminology are retained. See the measurements guide. Period preparation and storage methods are not modern safety guidance.
