How to Make It
In a saucepan, combine the wine, vinegar, sliced shallots, garlic, parsley, thyme and peppercorns and bring to a boil. Cook over moderate heat until reduced to 1/2 cup, about 20 minutes. Strain into a bowl. Stir in the lemon juice, season with salt and refrigerate until chilled.
Add the crème fraîche to the wine reduction and beat until soft peaks form, 1 to 2 minutes. Transfer the dip to a serving bowl; garnish with chives, shallot and grated lemon zest. Serve with potato chips and celery salt for sprinkling.
