Instructions with Photos

STEP 1: Rinse the lentils in a colander with running water and pour them into the pot. Fill with water about three times the volume of the lentils. Add the bay leaves, cover with a lid and bring to a boil. 

STEP 2: Turn down the heat on the stove and cook the lentils according to the manufacturer's instructions until tender.

STEP 3: Drain the cooked lentils, set the broth aside in a bowl for now.

STEP 4: In the meantime, prepare the roux with the onions.

Peel and finely chop the onion. Heat the lard in a non-stick frying pan and fry the onions until golden brown. Add the flour and fry for a further 2 minutes, stirring constantly.

Slowly add the lentil broth in batches, stirring well to prevent lumps from forming.

Finally, turn down the heat and let the onion roux slowly cook for about 15 minutes. Stir from time to time.

STEP 5: Add the cooked lentils. Only now salt, add vinegar and a pinch of sugar. Stir well.

If necessary, season more. Remix everything, and the dish is ready.

Serving

Finished lentils are served warm, usually with several types of side dishes that can be freely combined.

Here are the most typical examples of sides:

1. Pickles; one or two pickled cucumbers in sweet and sour brine with dill.
2. Fried onion rings, browned in oil or lard, lightly salted. The onion is placed on the lentils as a garnish.
3. Fried egg; roughly one egg per serving. As a final touch, garnish the egg with a sprig of green parsley.
4. Smoked sausage; cut in half and fried in a pan. You can serve a slice of smoked meat instead.
5. Rye bread; you can also serve the "čočka na kyselo" lentils with a slice of fresh rye bread.

Storage

These sour-style lentils should be served immediately after preparation. Over time, the lentils will absorb the sour taste of the vinegar, and the dish becomes bland.

If you have any lentils leftover, let them cool completely, cover with cling film, and store them in the fridge. The next day you can use it to make a tasty spread or lentil soup.

Cooking Tips

• Classic dried brown or green lentils are best suited for this dish. Do not use red lentils, as they are easily overcooked. Do not use canned lentils either.
• Vinegar is generally added only when the lentils are finally seasoned, not before. White wine vinegar, which does not have a very pungent taste, is best. Always add the vinegar carefully, then stir and taste.
• I use one medium onion, one tablespoon lard, one tablespoon all-purpose flour, and one cup lentil broth to make roux for the "čočka na kyselo" lentils for four people . This ratio has worked well for me to make the lentils just the right thickness.
