Smoky and Zesty Cameroonian (Central African) Beef Kabobs/ Brochettes a la camerounaises

I love Cameroonian food!  I love the deep, smoky, spunky flavor of the grilled meats with the sweet plantains, the everything!  The blend of ginger, garlic, onion along with tomatoes and hot peppers give Cameroonian food its unforgettable punch.  I have loved it and I have dreamed of recreating the delectable Central African flavors at home from the time I tried this lovely cuisine at the old Roger Miller restaurant that was once in Silver Spring, MD.  I was finally able to get my hands on some great recipes.  Although I searched for good recipes before, to no avail, I never thought to search in French.  Hello!  I had much better luck this time.

Below is one of the first Cameroonian recipes that I tried at home.  It is super easy to make and you can do it with things that you likely already have in your kitchen.  The flavor is deep, smoky, not-too-spicy, and has the perfect bite from the vinegar.  You'd never recognize the cayenne.  The blend of spices creates a delicious flavor that you and your family won't forget!

Cameroonian Beef Kabobs/ Brochettes a la camerounaises
1 lb beef (cut into bite-sized pieces) (use a cut that is good for kabobs)
1 white or vidalia onion
1 TB fresh ginger
5 cloves of garlic
2 chopped tomatoes or 1/2 can tomatoes in tomato sauce
1/4c apple cider vinegar
1 tsp salt
1 tsp cayenne pepper
3 TB oil

1. Blend all marinade ingredients into a homogeneous paste with a mortar and pestle or in the blender.  You do not want any chunks.

2. Pour marinade over meat and allow to marinate under refrigeration for a minimum of three hours, but ideally overnight.

3. Grill along with chopped onion and bell peppers on skewers that have been soaked in water for at least an hour (prevents burning).  Don't forget to brush your veggies with oil so that they cook nicely.  Enjoy :).
