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.

Cheese from Basque Country and northern Navarre, Spain
Idiazabal PDOIdiazabal
Raw milk of Latxa and Carranzana sheep is set with animal rennet at 28–32 °C, cut to grains 5–10 mm across, warmed to 35–38 °C, pressed and salted. The wheels ripen at least 60 days at 8–14 °C, and some are smoked over untreated wood a few days before sale. Made in 7 steps over 2 months. The longest step, ripen, takes at least 2 months (Ministerio de Agricultura 2022) and runs at 8–14 °C (Ministerio de Agricultura 2022). Lactococcus and Lactobacillus does most of the fermenting.
No fixed amounts recordedThe specification fixes temperatures, times and wheel sizes but no amounts. A finished wheel weighs 1–3.5 kg (± 10 %), 10–30 cm across and 8–12 cm high.

What makes this one different
Idiazabal may only use raw milk from two local breeds, Latxa and Carranzana. Smoking is optional; it began by accident in shepherds' huts without chimneys and is now done on purpose, over untreated wood, a few days before sale.
Milk
Raw milk of Latxa and Carranzana sheep
Ripening
At least 60 days
Composition
At least 45 % fat in dry matter, at least 55 % dry matter, at least 25 % protein in dry matter, pH 4.9–5.5
Shepherds made the cheese in summer huts in the Urbía and Aralar ranges and sold it at fairs; the town of Idiazabal in Goierri gave its name. Medieval rules for shared upland pastures survive. Traditional making ran mainly from March to June.
