We had some mole poblano from our friend Nacxi Gaxiola of xillinyc.com stashed in our freezer. Rich and complex, it’s the perfect thing to have on hand. It transforms the simple into the sublime, as it did for our lunch today. Pot-roasted chicken with mole poblano, black beans, and slices of avocado. We’ll have to replenish our stash of this “king” of sauces. It’s too good live without.
