@Animalz – Sweet dark chocolate mole sauce doesn’t sound bad. I make a white chocolate mole and I use white chocolate chips, which are very sweet. It’s really delicious! I use a lot of onion and garlic in my recipe, too. I also use animal crackers and lots of nuts.
Do you sauté the onions and garlic, and just toss them into the sauce? That might be the problem. I sauté the onions, garlic, and peppers. Then I toast the nuts in the oven and grind everything up in a food processor.
I strain all that into a blender with some butter and melted white chocolate chips, and blend it up.
Try grinding and straining your ingredients with the sweet dark chocolate and you might like what you end up with.
