Beef Picadillo

I've always loved recipes that incorporate sweet and savory in a perfect blend and this picadillo completely satisfies that balance.

1 tbsp olive oil
1 yellow onion
1 lb ground beef (90% lean)
2 cloves garlic, minced
1/34 c beef broth
28 oz canned diced tomato's with juice
1/4 red wine vinegar
2 tbsp tomato paste
1/2 c raisins
2 tbsp chili powder
1/2 tsp allspice
3/4 tsp cinnamon
Heat oil over medium high heat in a large pan. Add the onion and saute until translucent, about 4 minutes. Add the ground beef and cook down, breaking up clumps until the meat is brown. Stir in garlic and chili, allspice and cinnamon and cook for about 2 minutes. Add the tomatoes and juice, broth, vinegar and paste. Cook for about 5 minutes and then add the raisins. Raise heat to bring entire pot to a simmer and then reduce to medium and cook, uncovered for about 25 minutes or so until the picadillo is thickened.
