Ingredients:

• Shallots, finely chopped
• Champagne vinegar
• Sugar
• Sparkling white wine
• Black pepper

Directions:

Mix shallots with champagne vinegar, a dash of sugar, a sprinkle of cracked black pepper and a splash of sparkling wine. 

Pro tip: Make your mignonette the day before you plan to serve it. The flavors will meld together in the refrigerator overnight. Save the sparkling wine until right before you're ready to enjoy.
