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.
Ricotta is a boundary entry, set by heat and acid, not by microbes. Fat cow whey left from caciocavallo or scamorza is salted at about 1 kg per 100 litres, enriched with a little whey cream and heated to 82–85 °C, where a soured farm whey makes the proteins rise as flakes. The flakes are ladled into baskets on a sloping table and the creamy, straw-yellow ricotta is sold at once.
Amounts from a sourceThe regional sheet gives the salt dose per 100 litres of whey; there is no fixed batch size. Ricottas are sold in 0.5 kg and 1 kg baskets.
Fat cow whey from pasta filata cheesemaking (caciocavallo or scamorza)
A soured farm whey (pH 4–4.5) is added as the acid if the whey is not acid enough; no culture is described.

Ricotta is a boundary entry, set by heat and acid, not by microbes. Fat cow whey left from caciocavallo or scamorza is salted at about 1 kg per 100 litres, enriched with a little whey cream and heated to 82–85 °C, where a soured farm whey makes the proteins rise as flakes. The flakes are ladled into baskets on a sloping table and the creamy, straw-yellow ricotta is sold at once. Made in 4 steps over 10 min. The longest step, heat and add the acid whey, takes at least 10 min (Regione Campania 2017) and runs at 82–85 °C (Regione Campania 2017).
A rich ricotta from fat whey with whey cream added, salted in the vat and set with soured farm whey. The regional sheet says its straw-yellow colour comes from the fat, and describes the texture as soft and buttery.
Rind
None; pale straw, glossy from the fat, with basket marks
Size
Truncated cone of 0.5 or 1.0 kg; the 0.5 kg form is lower
The regional sheet notes that holding the whey above 82 °C for at least 10 minutes, with cleaned and disinfected vats, tables and baskets, is what the sheet gives as its guarantee of the ricotta's microbiological and hygienic quality. It is not ripened and is kept cold for only a short time.
The regional sheet traces the ricotta to at least the mid-1800s. A Montella cheesemaker held one of the first Italian export licences in the 1950s, and his son later made ricotta, treccia and scamorza in Bridgeport in the United States.
