large eggs (hard-boiled, cooled & halved)
6 slices bacon (cooked crisp & crumbled)
2 teaspoons fresh chives
2 teaspoons white vinegar
2 tablespoons finely shredded mild cheddar cheese
1⁄4 cup sour cream or 1⁄4 cup buttermilk
Transfer egg yolks from halves to mixing bowl & combine with remaining ingredients.
Add the sour cream or buttermilk last & use more as needed to reach desired smoothness.
Spoon yolk mixture into halves. The bulk will have grown substantially, so pile it high & "dust" with a sprinkle of paprika.
