Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Whole heads of white cabbage are cored, salted in the core and packed tightly in a barrel under brine and a stone. Over one to several weeks lactic bacteria sour them, while the brine is drawn off at the bottom and poured back over the top. The whole sour leaves are used to wrap sarma and sarmale, and the brine is drunk. Made in 4 steps over 7 days – 42 days. The longest step, ferment, drawing off the brine and pouring it back, takes 7–42 days (AGERPRES (Business OTS section) 2026) and runs at 18–22 °C (AGERPRES (Business OTS section) 2026). Salt is 6 % (Бексеев Ш.Г. (Bekseev Sh.G.)). Lactic acid bacteria, with the heterofermenters Leuconostoc mesenteroides and Lactobacillus brevis playing a smaller part in whole heads than in shredded cabbage and Leuconostoc mesenteroides in the first 3–5 days, then Lactobacillus plantarum do most of the fermenting.
Amounts from a sourceHousehold barrel tradition with no fixed batch size; the salt is a traditional Romanian brine ratio given in a 2026 article. A Russian whole-head method uses a stronger 6 % brine.

What makes this one different
The heads are fermented whole in brine, not shredded and dry-salted as in sauerkraut. The brine is drawn off and poured back during the ferment, and whole heads leave the heterofermenting bacteria a smaller part than in shredded cabbage.

Russian whole headsSmall cored heads in 6 % brine, or laid between layers of shredded cabbage salted at 2.5 %.
Safety
No authority limits specific to whole-head cabbage were found. The heads are kept fully under the brine and weighted down, and the barrel is moved somewhere cool once the cabbage is sour.
In Romania cabbage is traditionally put down between St Demetrius' Day (26 October) and St Andrew's Day (30 November). A 1962 study of Yugoslav fermented cabbage compared whole heads in brine with shredded cabbage.
