Uzbek cuisine is like mathematics, it is endless for learning and it doesn't fit into any books. Mastava is one of Uzbek dishes which is not often mentioned. But it deserves some attention. Shal we cook it right now?
There are only three main ingredients we surely need: rice, onions, carrots. A couple of spoons with vegetable oil is necessary too.
Lamb ribs are perfect for the dish. Put them into the pot and wait till they give some fat. If you do not have lamb ribs you can use beef instead. Cut it into pieces and fry till they become golden. By the way, you won't need much meat. If you want much meat, better make barbecue!
Do not fry the ribs too much, let them remain light.
Some onions and a bit of garlic are to be fried too. Add some water.
In fact you can experiment with the dish. For example, you can take a couple of carrots, pieces of turnip, a couple of tomatoes with their peel off and even an eggplant if you wish (did you know it can be boiled too?). Some pickle is not prohibited too.
