Get-Ahead Prep Steps

-- Stir together topping for the Brie the day before, and chill. Toast pecans up to two weeks ahead, and freeze in an airtight container.

-- Allow two days for beef tenderloin to thaw in refrigerator, if frozen.

-- Prepare Whipped Horseradish Cream eight hours before serving; cover and chill.

-- Trim and slice fennel for potatoes. Wrap in a damp paper towel, seal in a zip-top plastic freezer bag, and chill up to one day.

-- Make vinaigrette two days ahead. Cover and chill. Let stand at room temperature 30 minutes; whisk and serve.

-- Bake cheesecake one day ahead -- the texture is better when well chilled.
