Once tenderloins are seared, drain butter and add shallots. Cook until they are translucent. Remove pan from heat and add Amaretto. Be careful to avoid flare-up when returning pan to heat. Add demi-glace, currants and sun-dried tomatoes. Season with salt and pepper and place pan in oven.
Bake in oven to desired doneness, about 10 minutes for medium. Remove from oven and return pan to stove over medium heat, placing tenderloins on work surface. Whisk in butter and reduce sauce to smooth consistency. Slice tenderloins on the bias and arrange on plates. Spoon sauce over tenderloins and serve.
