Aarchi and kurut (Altai dried curd)
A two-stage Altai dairy preparation: sour chegen is heated into soft aarchi, then portions are drained, pressed and traditionally smoked into firm kurut.
Modern method
Low-moisture pizza mozzarella
An eight-litre cow’s-milk batch uses thermophilic culture and rennet before controlled curd acidification, hot-water stretching and chilling for pizza cheese.

Risks and precautions · Elevated risk
Fresh soft cheese contamination
The finished product is a fresh soft cheese; CDC describes Listeria risk in soft cheese and notes contamination can occur after pasteurization.
Hazard sourceThe source batch uses pasteurized milk and sanitizes equipment; these creator steps do not independently validate the final process or storage life.
Control sourceThe source's pH range is a stretchability target for this batch, not a safety limit.
The creator reports refrigerated storage for about 7 days and freezing; this is not a validated shelf life.
- Sanitize the stainless-steel equipment in boiling water for 15 minutes as the creator does. Set up a water bath and add 8 L pasteurized, unhomogenized cow’s milk.
- Heat milk in the water bath to 37°C. If using annatto for color, dilute 4–8 drops in 1/4 cup nonchlorinated water, add and stir it through; the filmed batch uses the color option.
- Sprinkle 1/8 tsp thermophilic culture over the milk. Rehydrate for 5 minutes, stir it in and ripen for 1 hour.
- Add 1/2 tsp single-strength rennet diluted in 1/4 cup nonchlorinated water while stirring. Stir for no more than 1 minute, cover and set for 1 hour; check for a clean break.
- Cut curd into 5 mm cubes and let them heal for 5 minutes. Check that the curd has acidified to about pH 6.4 as the creator does.
- Raise curd temperature to 38°C over 45 minutes while stirring gently and continuously. Let curds settle and hold at that temperature for 30 minutes, then drain and retain the whey.
- Keep the drained curds warm in the source’s 38°C whey bath. Begin pH checks after 30 minutes, then check every 15 minutes; the stated stretch range is pH 5.0–5.3. Although the creator initially allows about 2 hours for acidification, the filmed curd reaches pH 5.09 shortly after the first checks, before he salts and stretches it. This source batch does not acidify overnight.
- Break the curd into thumb-sized pieces. Weigh the curd and mix through noniodized salt equal to 2% of its weight; the source weighed 1,145 g curd and used 22.9 g salt.
- Heat water to 95°C as in the filmed method, pour it over the salted curd and stretch until smooth and elastic, using heavy rubber gloves. Form the cheese in a rectangular basket; press out gaps as shown and sprinkle 1 tsp salt on each face.
- Refrigerate the cheese in the basket. The creator removed it after about 12 hours when it started drying, wrapped it for a further 12 hours, and says the finished cheese keeps wrapped in the refrigerator for about 7 days or may be frozen. These storage statements are not validated.

How to Make Low-Moisture Mozzarella Cheese for Pizza at Home - ReduxThe source uses 8 L pasteurized, unhomogenized cow’s milk, 1/8 tsp thermophilic culture, 1/2 tsp single-strength rennet, and salt at 2% of curd weight. Milk ripens at 37°C; curds warm to 38°C and are stretched in 95°C water after the creator’s pH checks. The creator weighs 1,145 g of curd before stretching; finished yield is not stated.
