Celery Root and Quince with Olive Oil (Zeytinyağlı Ayvalı Kereviz-nimbuls)

It's the season for celery roots, aka celeriac, and quinces and these two go marvelously well together in this Aegean inspired dish.

1 celery root, ~1,5-2 lb, peeled and cubed
1 quince, peeled and cubed
1 carrot, peeled and cut in half moons
1 medium onion, finely chopped
juice of 1 lemon
1 tsp sugar
1-1,5 tsp salt
2 tbsp flour
1/4 cup olive oil
1/4 cup finely chopped celery leaves, parsley, or dill

-In a mid size bowl, mix 4 cups of water, lemon juice and flour.
-Place the peeled and diced celery root in the water and stir. If the water doesn't cover the celery root, add more water.
-Heat olive oil in a wide pot and add onions.
-Stir until soft, 8-10 minutes, but do not let them brown.
-Add sugar and stir.
-Add carrots and cook for 2-3 minutes.
-Take the celery out of the lemon-flour water with a slotted spoon and add to the pot. Preserve the water.
-Add quince.
-Add 1 cup of the water with lemon and flour to the pot. Top it with regular hot water until the vegetables are barely covered. (For a different taste, top with orange juice)
-Salt to taste.
-Simmer covered on medium for 20-25 minutes.
-Turn it off and let cool down to room temperature in the pot, covered.
-Once at room temperature, bring it to a serving plate and sprinkle with finely chopped celery leaves, parsley, or dill.

Olive oil dishes are always served at room temperature. They're even more flavorful the second day.
Enjoy with a splash of lemon juice on top, with crusty bread or rice, or on its own.
