The Kathmandu default — buffalo mince, a thicker wrapper and a darker achar.

Buff momo are filled with minced water buffalo, which is leaner and more strongly flavoured than chicken and stands up to heavier seasoning. The wrapper is usually rolled a little thicker to carry the denser filling, and the achar served with it is darker and more sesame-heavy.
Buffalo is the everyday red meat of the Kathmandu Valley, where cow slaughter is prohibited and goat is expensive, so buff momo is what most momo shops in the city actually sell. Outside Nepal it is harder to find, and Nepali restaurants abroad often substitute lamb or beef — worth asking, because the flavour is noticeably different.
The same method as any momo: lift by the pleats, bite a small opening at the side, and take the juice first — buff momo hold more liquid than chicken, so this matters more here. Dip the opened side into the achar rather than submerging the dumpling. A squeeze of lime over the plate cuts the fat. If you are offered jhol, a thin spiced broth, pour a little into the plate and eat the momo sitting in it.
Knead the flour with about 160 ml water and a pinch of salt until smooth, then rest covered for thirty minutes so it rolls without springing back.
Mix the buffalo with the chopped fat, onion, garlic, ginger, timur, ground spices, coriander leaf and salt. Buffalo carries very little fat of its own, and without the addition the filling steams dry and crumbly.
Roll circles about 8 cm across, a little thicker than you would for a chicken momo. The denser filling tears a very thin wrapper during pleating.
A heaped teaspoon per wrapper, pleated around and pinched hard at the top. Check each seal — buff filling releases a lot of liquid and an open momo empties itself.
Slightly longer than chicken, on an oiled tray over rolling water. Red meat needs the extra time and the wrapper is thicker.
Char the tomatoes until blackened, then blend with a heavier hand of toasted sesame and more dried chilli than the chicken version takes. It should be thick, dark and hot enough to answer the richness of the meat.
