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.

Pasteurised ewe milk from the lower Sabina is soured with a mesophilic starter and set with lamb or calf rennet at 36 °C. The curd is broken to walnut size, cooked briefly at 38 °C, shaped into low square blocks, brined and warmed twice at 43 °C. The blocks ripen 20–30 days at 13 °C with potato starch dusted on their faces; the herb version has rocket, olives, radicchio or chilli in the curd. Made in 9 steps over 20 days – 30 days. The longest step, ripen with potato starch, takes 20–30 days (ARSIAL (Lazio regional agency for agricultura…) and runs at 13 °C (ARSIAL (Lazio regional agency for agricultura…). Mesophilic lactic starter cultures does most of the fermenting.

What makes this one different
A young ewe cheese shaped as a low square block, not a round. Its faces are dusted with potato starch while it ripens, which gives the rough grey rind.
Rind
Rough and greyish from the potato starch
Size
Rectangular block with a low side, about 1.2–1.5 kg

Safety
The milk is pasteurised at 70 °C for 20 seconds before the starter goes in. The Lazio list marks it as allowed to use derogations from the standard hygiene rules for its traditional methods.
The cheese was revived from the oral tradition of the lower Sabina and from old documents in town archives; it has been sold in local shops and restaurants for at least 25 years. A legend says Charlemagne tasted it at Farfa Abbey on his way to be crowned in Rome.
