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.

Raw whole cow milk is set with animal rennet at 28–33 °C, cut into 2–4 cm cubes and gathered in cheesecloth to drain under its own weight, then pressed for 4–6 hours. The pressed cake is sliced, layered with salt in a tub and weighted, so its own whey rises and covers the slices. They ripen under that whey at 15–25 °C for at least 15 days. Made in 7 steps over 15 days. The longest step, ripen under whey, takes at least 15 days (Udruženje proizvođača NVO 'Pljevaljski sir' 2017) and runs at 15–25 °C (Udruženje proizvođača NVO 'Pljevaljski sir' 2017). Leuconostoc mesenteroides does most of the fermenting.
Amounts from a sourceThe specification gives no amounts except the top-up brine strength. Slices are 1.5–3 cm thick.

What makes this one different
The slices ripen in their own salted whey, pressed out of the cheese in the tub, rather than in a made-up brine; a brine is added only when the whey runs short. It is made from raw cow milk with nothing but rennet and salt.
Composition
Salt at most 4 %; fat at least 45 % of dry matter
Storage
Kept cold, below 10 °C, and dark, for at most 60 days
Made from raw milk with no starter. The specification limits salt to 4 %, keeps ripening anaerobic under whey and requires storage below 10 °C for no more than 60 days.
The specification says the cheese was once made in special huts (mljekari) and is now made mostly in rooms set aside within the farm household. Pljevaljski sir has long been the name for white brined cheese in Montenegro.
