Aged salted clarified butter, fermented underground in clay jars 1 to 12 months. Pungent, blue-cheese-funk. The hidden weapon in couscous and tagine.
Berber preservation craft pre-dating refrigeration — Atlas Mountain villages buried clay jars (khabia) of salted clarified butter to age through winter. Southern Moroccan Berber families traditionally buried a sealed jar on the day a daughter was born, unearthing it 18-25 years later to season her wedding feast — decades-aged smen prized as the finest cooking fat, shared only with honored guests. Maghrebi diaspora keeps it alive in Marseille and Paris North African groceries.
Authentic underground-aged smen is rare even in Morocco today; most jarred supermarket versions (e.g., the Le Pélican brand) are short-aged surface ferments. The Imilchil annual moussem (a Berber market festival in the High Atlas) still sells village-made smen by the kilo. Indian niter kibbeh and Yemeni samna are spiced cousins, not the same thing.
Color of dirty cream, separating into oil and curd. Smell hits like a cheese cave — barnyard, ammonia, lactic. Taste is salty-funk-fat, mellower than the smell suggests. A teaspoon stirred into couscous transforms broth into something feral.
Cooked unsalted butter is clarified to remove milk solids, then heavily salted (5-10% by weight) and packed airless into a clay jar. Anaerobic fermentation by lactic bacteria and yeasts at cool earth temperature (12-15°C) drives lipolysis — fats break to free fatty acids that read as the funk. Aerobic exposure during aging spoils it.
Variations
Moroccan Berber smen (longest-aged, most pungent — Imilchil and Middle Atlas standard) vs. Tunisian zammita-paired smen (lighter, kitchen-aged) vs. Algerian dhen (often cow-and-sheep-milk blend). Yemeni samna baladi and Egyptian samna are clarified-butter cousins without the long ferment.

- 130 min
Make ghee from 500 g unsalted butter — simmer until milk solids brown.
Watch outSimmer the butter until the milk solids at the bottom turn golden and smell nutty — that's clarified and ready to strain.
- 25 min
Strain hot ghee into a clay or glass jar; stir in 30 g coarse salt while warm.
Watch outSalt it heavily while still warm and pack it airless — any trapped air during aging spoils the whole jar.
- 35 min
Cover loosely with cloth; bury jar in cool dry earth or store in cold cellar.

Age 1–12 months until pungent, blue-cheese funky; use sparingly in tagines.
Watch outIt's ready when it turns sharply pungent, like blue cheese — that funk is the sign, and a little goes a long way in a tagine.
