Why the temperature you cook at decides what you eat
Cooking usually kills the cultures you fermented butter to get. Fat shields them from heat, so a 55 to 60C cook keeps them live to the plate.

What to add to a chamber vac ferment, and why most home recipes get it wrong
Most home ferment recipes assume you can take a crock-style spice blend and bag it. You can’t. The bag changes which aromatics survive, which get wasted, and which the bacteria actually use to build flavour.

Salt, bag, time, system. The chamber vacuum method end to end.
Three Field Notes covered the variables. This one is the protocol that uses all three. The Neutral Base Method, every step from raw cabbage to refrigerated jar.

Salt, bag, time. The third variable runs the biology.
Salt sets the chemistry. The bag delivers the pressure. Time runs the biology, and the chamber vac does not let you skip it. Days, not weeks. Never hours.
-
Salt, pressure, time. Now: the bag.
Bag thickness, seal width, and food-grade specs decide whether the ferment works. The second variable in the chamber vacuum system, and why most home setups underspecify it.

Chamber vacuum fermentation vs. airlock jars: the pressure physics that change what your ferment produces
Chamber vacuum fermentation and traditional airlock jars start with the same ingredients. The physics of what happens next is completely different. Here is why pressure changes what your ferment produces.
