3 lbs. short ribs (boneless will work if that’s all you can find, but bones add nutrition & awesome flavor!)
3 T butter
3 stalks celery, diced
1/2 yellow onion, diced
2 carrots, diced
4 cloves garlic, chopped
4 oz. mushrooms, roughly chopped
handful of sage, rosemary and thyme, chopped
1 qt. chicken stock

1/4 c apple cider vinegar
