1. Place tomatoes and capers in the bowl of a food processor and process until coarsely chopped.
2. Prepare your favorite challah recipe. Brush an egg wash on the challah which has already been shaped and has risen.
3. Schmear the tomato mixture carefully over the challah so as not to deflate challah.
4. Sprinkle with the black garlic granules.
5. Bake normally in a 350-degree-Fahrenheit preheated oven (about 25 minutes for a medium challah).
