Slice across the grain
Thin strips with short fibres are easier to chew. Remove long firm sinews before slicing.
Buckwheat cooks separately. Beef is briefly browned, leek then softens, and the meat finishes cooking fully in the sauce.
Why this recipe works
Beef rump is sliced thinly across the grain. Leek supplies the vegetables in a quick cream sauce with a little mustard. Buckwheat stays separate and is fluffed gently. The quantity makes two complete main meals.
Recipe
Thin beef strips and tender leek in a mild mustard cream sauce, served with fluffy cooked buckwheat.
Split leek lengthways, wash thoroughly between layers and cut into thin rings. Finely dice onion. Slice beef across the grain into strips about 0.5 cm thin and pat dry.
Rinse buckwheat in a sieve. Bring to a boil with 280 ml water and half the salt, cover and cook over low heat according to the package for about 15 minutes, then let stand off the heat for 5 minutes. Fluff with a fork.
Meanwhile heat half the oil in a large pan. Brown meat over medium-high heat for about 3 minutes, turning, then transfer to a separate plate. The strips are not yet fully cooked.
Add remaining oil to the pan. Soften onion for 2 minutes, then add leek and remaining 120 ml water. Cover and cook tender for about 8 minutes. Stir in cream, mustard, remaining salt and pepper.
Return beef and collected juices to the sauce and simmer gently over low heat for about 6 minutes. The centre of the thickest strips must reach at least 70 °C for 2 minutes; check with a thermometer and cook longer if needed. Serve hot immediately with fluffy buckwheat.
