Meat and Potato Stew

300 grams (approx. 10.6 ounces) of beef
500 grams (approx. 17.6 ounces) of rosticciana (pork ribs)
500 grams (approx. 17.6 ounces) of potatoes
300 grams (approx. 10.6 ounces) of peeled plum tomatoes
1/2 cup of extra virgin olive oil
1/2 cup of wine red
2 garlic cloves
1 sprig of rosemary
salt and pepper

Cut the meat into pieces. Peel the potatoes and cut them into cubes. Put all of the ingredients together in a saucepan. Put it on medium heat and let it cook for about two hours until the liquid has evaporated, without ever mixing it. Tie the rosemary together with a string so it doesn't loose its leaves. It is best to use an earthenware pot.
