Roasted & charred
Borts
борц · Borts is a traditional Mongolian air-dried meat preparation in which lean fresh meat is trimmed, sliced into long narrow strips, threaded on cord, and suspended under the shade of a ger (yurt) roof for roughly one month, where it slowly loses moisture through passive airflow until it becomes a hard, dark brown stick of preserved meat that functions as a long-lasting nomadic staple or reusable ingredient rather than a finished dish.
The formula
1 kg fresh lean meat yields ~250–300 g finished borts (~3–4:1 reduction)
Pure single-ingredient preservation — no salt, smoke, or liquid; shade-drying alone concentrates flavor and extends shelf life to nearly a year.
Identity
- Air-dried in the shade — never roasted, smoked, charred, or salted
- Cut into long strips 2–3 cm thick × 5–7 cm wide, ~30 cm long
- Hung on cords under the roof of a ger where cool dry air circulates freely
- Drying process known as 'bortslokh' (борцлох)
- Practically unsalted — a defining characteristic
- Functions as a reusable preserved staple, not a finished plate dish
Ingredients
| Base | Lean fresh meat (beef or mutton — most common) | All membranes, silverskin, tendons, and external fat must be trimmed off before slicing. |
| Base | Horse meat (конина) | Traditionally preferred; its yellowish fat is believed to warm the body more than other meats. |
| Base | Yak, camel, or reindeer meat | Regional substitutions — camel in the Gobi, reindeer and yak in the north. |
| Seasoning | None added (no salt, no smoke, no spices) | Sources confirm borts is 'practically unsalted' (практически совсем не соленое); flavor comes purely from the meat and slow air-drying. |
Method
- 1Trim fresh meat of all membranes, silverskin, tendons, and surface fat.Connective tissue and fat resist drying, can oxidize, and trap moisture that promotes spoilage during the long ambient hang.
- 2Cut the meat into long strips ~2–3 cm thick × 5–7 cm wide, ~30 cm long.Uniform narrow strips expose maximum surface area for even airflow; the thickness prevents case-hardening while still allowing thorough dehydration.
- 3Thread the strips on cord and hang them under the shaded eaves or roof of a ger where cool dry air circulates.Shade protects fat-soluble compounds and prevents surface cracking; the ger roof's natural breeze delivers the cool, dry microclimate nomadic cooks rely on.
- 4Leave the strips to air-dry for approximately one month, until they shrink into small, hard, dark brown sticks.Slow passive dehydration reduces water activity below the microbial-growth threshold, producing a shelf-stable product without salt or smoke.
- 5Remove the dried strips from the cords once they are firm and rock-hard; transfer to dry storage.Residual softness signals incomplete drying and mold risk; the rock-hard end-texture confirms a safe shelf life of up to nearly a year.
Techniques that matter
Shade air-drying under a ger roof
The elevated, shaded eaves create a naturally cool, breezy, low-humidity microclimate ideal for slow dehydration without heat damage.
Threading strips on cord for suspension
Suspension keeps every surface exposed to moving air and prevents pieces from touching, which would trap moisture and cause rot.
Strict removal of membranes and fat before hanging
Lean muscle dries safely; fat and connective tissue oxidize and spoil first, so they must be removed for a shelf-stable result.
Variations & derivatives
Beef or mutton bortsCentral and eastern Mongolia
The everyday, most accessible form using domestic herd animals.
Horse-meat borts (koniin borts)Mongolian steppe
Traditionally prized for its warming yellow fat.
Camel-meat bortsGobi Desert region
Made from local camelids where horses and cattle are scarce.
Reindeer or yak bortsNorthern Mongolia
Cold-climate variant using the meat available to northern herders.
Used in these dishes
Substitutions
- Beef → Horse meat — Most common swap; preferred for warming properties.
- Beef → Mutton — Direct regional equivalent in most Mongolian households.
- Beef → Camel meat — Traditional only in the Gobi where camels are the local herd animal.
- Beef → Yak or reindeer meat — Northern substitute; flavor is leaner and more gamey.
Troubleshooting
Mold appears on hanging strips
Humidity too high or insufficient airflow under the roof. → Relocate to a drier, breezier spot and trim off visibly moldy sections; reduce strip thickness slightly so they dry faster.
Meat stays soft and pliable after a month
Strips cut too thick or hanging spot too cold/damp for active drying. → Re-slice closer to 2 cm thick and move to a spot with stronger, drier air movement.
Surface case-hardens while the interior stays wet
Direct sun or warm wind dried the outside too fast, sealing moisture inside. → Always dry strictly in shade under the ger roof, never in direct sunlight; discard any batch that has crusted over.
Strong off or rancid odor during drying
Insufficient trimming of fat and silverskin before hanging. → Discard the batch and start over with all external fat and membranes cleanly removed.
