Uzbek marinade and sauce

This sauce/marinade is so so good. It is robust, flavorful but not to spicy. I have used it with lamb, chicken and steak and it all works fine. It can be used as a marinade or as a sauce. If using as a marinade make sure to brush of the marinade before putting it on the grill to make sure it sears nicely and develops the good char on the outside.

Ingredients;

1 small yellow onion
4 canned plum tomatoes (or any canned tomatoes you have in the house, if you use chopped tomatoes make sure you drain them first and then add the juice to the marinade after until desired thickness, if using whole plum tomatoes take out the tomatoes, keep the juice for later to add for desired thickness)
1/2 cup extra-virgin olive oil
4 large garlic cloves coarsely chopped
2 tbs red wine vinegar
1 tbs sweet paprika (powder)
1 tbs dried thyme
1 tbs ground coriander
2 tsp ground cumin
2 tsp salt
1/2 tsp cayenne
1/2 tsp freshly ground pepper

In a food processor or the bowl attachment to a hand blender like the Braun process the marinade ingredients until very smooth. 

Mmmmmmm!
