Pork Stew with Leeks and Plums

This is a recipe from the region of Macedonia, in Northern Greece. It was posted on Google+ by Xaris Xaris and I was given permission to translate it. Enjoy!

Ingredients

1 kilo of pork meat, preferably from the shoulder, cut in pieces
1 kilo of leeks, only the white part, cut into slices
5 tablespoons celery, finely chopped
1 small onion, finely chopped
1 level tablespoon tomato puree
10 dry plums, cut in halves
¾ of a cup extra virgin olive oil
salt, freshly ground black pepper

Saute slightly the onion with the olive oil, add the pork and let it get golden brown on all sizes. Add 1 cup of hot water, a little salt and let it simmer for about 30 minutes. Take the pork out of the pot and keep it warm on a large plate. Add the leeks in the pot (if you like you can blanch them before), 2 cups of water, a little salt and cook on medium temperature for another 25 minutes. Finally, put the pork back in the pot with the leeks, add the tomato puree dissolved in a little water, the plums and the celery. Stir only once and simmer for another 20 minutes until most of the liquid is evaporated and there is only a thick sauce in the pot.
Serve this dish warm with freshly ground black pepper on top.
