Chef Big DPrecision-roasted fingerling potatoes bathed in a high-viscosity smoked mascarpone and sage butter emulsion. A masterclass in texture and subtle smoke.
Preheat your oven to 425°F (220°C). Toss the halved fingerlings with olive oil, salt, and pepper on a large sheet pan. Ensure they are in a single layer, cut-side down, for maximum Maillard reaction.
Uniformity is king. If they aren't the same size, they won't roast at the same rate.
Roast the potatoes until the skins are wrinkled and the cut sides are deeply golden and crisp.
Don't crowd the pan or they will steam instead of roast.
While the potatoes roast, melt the butter in a copper saucier or small skillet over medium-low heat. Add the sage leaves and fry until they are crisp and the butter begins to turn a nutty brown. Remove from heat immediately.
Watch the butter closely; the transition from brown to burnt happens in seconds.
Whisk the liquid smoke and lemon juice into the brown butter. Slowly fold in the mascarpone, whisking constantly to create a stable, velvety emulsion. The residual heat should be just enough to melt the cheese without breaking the fats.
If it starts to separate, add a teaspoon of warm water and whisk vigorously.
Transfer the hot roasted potatoes to a warmed bowl. Pour the smoked mascarpone sage butter over them and toss gently to coat every crevice. Serve immediately while the emulsion is at peak viscosity.
Plate with the crispy sage leaves on top for a textural contrast.
The key to this dish is the emulsion of the mascarpone into the sage butter. If you add the mascarpone too quickly or to a pan that is too hot, it will split. Look for a 'velvety' viscosity. Inspired by the precision of French saucier techniques and the rustic soul of Italian sides. This dish almost caused a mutiny once because I insisted on slicing each fingerling to a tolerance of 0.5mm—don't be that guy, but do keep them uniform.
