hi. so sunday is my best friend's birthday and i am cooking for eight people of her choosing and i want to make something special. i picked up an absolutely gorgeous beef tenderloin today which i would like to roast whole. anyone have any ideas for a lovely sauce to go with this - preferably do ahead - so i can have a few glasses of wine whilst putting the rest of the meal together (roasted asparagus, roasted cherry tomatoes with thyme, garlic mashed potatoes and a greens/beet salad witha citrus vinaigrette).
thanks for any help you might be able to give me,
