Preheat oven to 325F
Heat a heavy bottomed sauté pan over high heat.
Season short rib liberally with salt and pepper.
Sear the beef on all sides until golden brown, and remove from pan.
In the same pan add garlic, herbs, and mirepoix.
Saute together for 2 minutes, deglaze with the red wine, and then add the chicken stock and san marzano tomatoes.
Transfer the mixture to a deep pan and submerge the seared short rib in the braising liquid.
Cover with aluminum foil and place in the oven to braise for roughly 3 hours.
After 2 ½ hours have passed, place the potato in a pot of water and cook until tender.
Once the potato is tender strain off the water and pass the potato through a food mill.
Warm the cream, and add it to the potatoes along with the crème fraiche and butter.
Fold gently until a smooth consistency is achieved, season with salt.
Remove the short rib from the braise and strain the braising liquid.
Place 4 oz of the liquid and cipollini onions in a sauté pan and reduce by half.
In a small bowl mix the ramps, heirloom tomato, olive oil, lemon juice and balsamic vinegar.
Place the crème fraiche potatoes on the plate.
Top with the braised short rib.
Spoon the braising liquid over the top and garnish with the ramp and tomato salad.
