Rinflajš with boiled beef, root vegetables and tomato sauce
Rinflajš sa paradajz sosom is less a single-pot stew than a coordinated way of using one long simmer to produce several parts of a meal. In the Vojvodina Sunday-lunch tradition, beef and root vegetables cook slowly in water to create a clear, savoury broth. The broth can be served first, while the cooked meat and vegetables become the main course with a separate sauce.
Beef shoulder suits this method because connective tissue softens during a long, quiet simmer. A rolling boil works against the desired result: it agitates proteins into the broth, makes the liquid cloudier and can leave the meat tight before the connective tissue has relaxed. Gentle bubbling gives the shoulder time to become tender while keeping the vegetables recognisable.
The vegetables are added in stages because they do not all tolerate two hours of cooking. Carrot, celeriac, parsley root and onion can flavour the broth for much of the simmer. Potatoes are added later so they become tender without disintegrating. This sequencing is what lets the same pot produce both a useful soup and a plate of intact vegetables.
The tomato sauce is prepared separately rather than turning the broth into a tomato stew. Butter and flour form a pale thickening base; the flour needs a short cook before tomato juice and reserved broth are whisked in. That brief step removes raw-flour flavour without browning the roux, so the finished sauce stays bright and smooth rather than nutty and dark.
A small amount of garlic, sugar and broth rounds the acidity of the tomato without making the sauce sweet. The sauce should coat a spoon and flow over slices of beef, not sit as a dense paste. Reserved broth is especially useful here because it carries the same beef-and-root-vegetable flavour as the main dish and links the components on the plate.
The meat is safely cooked once it has exceeded 63 °C, but this dish continues far beyond that point because tenderness, not minimum temperature, determines doneness. The final plate should show sliceable but yielding beef, soft vegetables that still hold their shape and a tomato sauce smooth enough to bind each bite without masking the broth-cooked character of the meat.
