Canned Chipotle Peppers in Adobo Sauce are simply very ripe jalapeno peppers that have been dried, smoked and packed in a sauce of tomatoes, vinegar, paprika, oregano, garlic and onion. If you’ve never cooked with them before, you’ll be shocked at what a shortcut they can be when wanting to add flavor to loads of recipes.
And, to make sure those flavors, and a couple of other ones in this marinade, really travel to the deepest parts of the chicken, buttermilk is a miracle...
Cooks in the south, like the ones I grew up with, always used buttermilk to tenderize and moisturize fried chicken...The acid in buttermilk helps break down the protein strings, which makes the bird more tender and succulent, while carrying those flavorful spices and herbs into the deepest part of the meat.
And this spicy version of the marinade those smart cooks have used for generations makes this chicken just as delicious and juicy…even though it’s grilled and not fried!
