Heat the olive oil in a saute pan over medium high heat.
Once the oil is hot, add the cipollini onions along with a pinch of salt and saute until caramelized.
Turn the heat to medium, add the red wine, water, vinegar, sugar, honey, and coriander. Allow the mixture to stew and reduce to a jam.
Add the stock along with a sprinkle of fresh thyme. Reduce by half. Taste and adjust the seasoning. This is the cipollini onion marmalade.
Warm the milk in a small pot over low heat.
Once the potatoes are cooked, drain them and allow to cool slightly.
Peel the potatoes and pass them through a ricer into a clean medium pot.
Cook the riced potatoes on medium low heat and beat them with a wooden spoon to dry them out.
Slowly beat 6 tablespoons of butter into the hot potatoes. Add the warm milk and switch to a whisk to whip the potatoes, they should be a silky consistency. Adjust the seasoning with salt, cover, and keep warm.
Season the steak on all sides with Truffle Salt or Rancher’s Steak Seasoning.
Heat a large saute pan over high heat. Add the remaining high heat oil to the preheated pan.
Just before the oil begins smoking, add the steaks and sear over high heat, flipping every 30 seconds or so until cooked to your desired doneness, about 2-3 minutes for a solid medium-rare.
Add the remaining butter. Smash the garlic clove and add it to the pan, along with the thyme. Use a large metal spoon to baste.
Transfer the steaks to a cutting board to rest, topped with the garlic and thyme.
Once the steak has rested, carve it into ½ inch thick slides.
Plate a nice dollop of potato puree onto the plate, lay the carved steak alongside, and top with the cipollini onion marmalade. Serve alongside some roasted carrots for an absolutely delicious steak dinner!!
