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.

Cow milk is soured by lactic starter cultures, slowly over 12–20 hours or quickly over 4–6 hours after pre-ripening, sometimes with a little rennet. The curd is chopped into walnut-sized lumps, warmed, cooled and drained only by gravity, so it stays in loose, moist lumps that look like cauliflower.

At a glance
Cow milk is soured by lactic starter cultures, slowly over 12–20 hours or quickly over 4–6 hours after pre-ripening, sometimes with a little rennet. The curd is chopped into walnut-sized lumps, warmed, cooled and drained only by gravity, so it stays in loose, moist lumps that look like cauliflower. Made in 7 steps over 10 h – 28 h. The longest step, curdle by souring, takes 4–20 h (Commission Implementing Decision of 19 March…) and runs at 22–32 °C (Commission Implementing Decision of 19 March…). Acidifying and aroma-producing lactic acid bacteria does most of the fermenting.
Rögös túró is the lumpy form of Hungarian túró. Its curd is soured by bacteria, chopped into large lumps and drained only by gravity, never pressed or kneaded, so the lumps stay whole and wet inside.
Texture
Loose lumps of 4–20 mm, like cauliflower, wet inside and filmed with whey
Fat grades
Full-fat (at least 60 % fat in dry matter) down to skimmed (under 10 %)
Dry matter
At least 40 % (full-fat) down to at least 15 % (skimmed)
Slow-curdling method0.5–1.5 % starter at 22–32 °C, 12–20 hours, warmed to 30–40 °C.
Fast-curdling methodMilk pre-ripened 6–8 hours at 12–15 °C, then 4–5 % starter at 30–32 °C for 4–6 hours, warmed to 36–48 °C.
Mixed curdlingA little rennet is added alongside the starter.
Safety
The specification cools the curd quickly to 18–22 °C to stop over-souring and the spread of contaminants, and keeps the finished túró below 6 °C. The specification allows raw or pasteurised cow milk. The CDC says people at higher risk, including pregnant women, people 65 or older and people with weak immunity, should avoid cheese made from raw milk unless it is heated to 165 °F (74 °C) or until steaming hot.
The specification cites ethnographic sources on 18th–20th century curd cheese kept by grinding it into grain- or hazelnut-sized pieces, a 1925 dairy text noting that crumblier curd keeps fresh longer, and a 1960 description of curd lumps "reminiscent of cauliflower". In 1980 the dairy scientist Sándor Szakály wrote that the lumpy type made up 80 % of Hungarian curd cheese. A 2001 text, quoted in a 2019 presentation by the Hungarian Milk Product Council, calls it an ancient Hungarian dairy product known only in Central Europe and made at home for centuries from raw milk. In 2002 it entered the Hungarian "Hagyományok Ízek Régiók" collection, which required a documented history of at least two generations (50 years). The EU registered the name as a TSG by Regulation (EU) 2019/1288 of 25 July 2019, published on 1 August 2019.
