Rassolnik

Rassolnik is a thick Russian soup with pickled cucumbers, and often pickle brine, that suits lunch especially well. The classic Russian version is made with pearl barley and a sauté of onion and carrot with tomato paste, and that is exactly the version prepared here. Rassolnik is the kind of soup to make when a warming, substantial bowl is wanted without turning to a very heavy stew.

Pearl barley gives rassolnik its classic body, while beef makes the broth richer and more filling. Pickled cucumbers bring the characteristic sharp and salty note that defines rassolnik, and tomato paste rounds out the base with extra depth. Potatoes make the soup heartier, while onion and carrot form the familiar vegetable foundation of the sauté.

Soaking the pearl barley in advance is important because soaked pearl barley cooks more evenly in the soup. The soaking can be done for several hours or overnight, and the water should then be drained off before the pearl barley is rinsed. When the pearl barley goes into the pot with 3 litres of water, the soup should first be brought to a boil and then cooked over lower heat for about 20 minutes before the potatoes are added.

The key thing to watch while cooking is the balance of texture and saltiness. The potatoes should be cut into small cubes so they become tender in about 15 to 20 minutes, and the pickled cucumbers should be added only after the potatoes are nearly ready. After the pickled cucumbers and tomato paste go in, the soup should be brought back to a boil, simmered for another 5 minutes, and tasted at the end: if the saltiness is not enough, pickle brine can still be added, and the flavour can also be balanced with salt and spices, including pepper.

Pearl barley can be replaced if needed, although pearl barley is the classic choice for rassolnik. The source notes that pearl barley is what makes the soup traditional, but rice, buckwheat or millet are common replacements when a different texture is preferred. Beef can be changed according to what is on hand, but the recipe here is specifically built around beef and keeps the classic direction of the soup.

Rassolnik is best served hot, straight after cooking, when the broth tastes bright and the vegetables still hold their shape. The finished soup is complete on its own as a lunch dish, and its thick texture means a moderate portion still feels substantial. A final tasting just before serving remains important, because the exact saltiness depends on the pickled cucumbers and can vary from batch to batch.

Rassolnik keeps well in the refrigerator for up to 3 days in a covered pot or container at 2 to 4°C. The source notes that the pickled cucumbers and brine act as a natural preservative, so rassolnik keeps slightly longer than an ordinary vegetable soup. Freezing is possible, but pearl barley becomes soft and slightly slimy after thawing, so the better option is to freeze the broth with the vegetables and cook the pearl barley separately before reheating.
