Ingredients 8 large eggs ⅓ cup mayonnaise 1 tablespoon Dijon mustard 1 teaspoon white-wine vinegar ¾ cup finely chopped watercress, plus leaves for garnish 2 teaspoons drained prepared horseradish Directions In a medium saucepan, cover eggs with 1 inch of water. Bring to a boil; remove from heat. Cover and let stand 12 minutes. Drain eggs; run under cold water until cool enough to handle. Peel and halve eggs lengthwise; remove yolks and transfer to a bowl. Mash with a fork; mix in mayonnaise, mustard, and vinegar. Press through a sieve to make smooth. Stir chopped watercress and horseradish into yolk mixture. Using a pastry bag fitted with desired tip (we used plain and star tips), pipe yolk mixture into whites. Garnish with watercress leaves. Serve immediately, or chill up to 2 hours. Cook's Notes Instead of piping the filling with a pastry bag and tip, you can use a resealable plastic bag with a corner snipped off. Or simply spoon it into the egg whites. Rate it Print
