Remove egg yolks and place in a medium bowl. Mash well with a fork. Stir in mayonnaise, 1 teaspoon red pepper jelly, dry mustard, cayenne pepper, and salt until smooth.
Spoon egg yolk filling into egg whites.
Top each one with about 1/2 teaspoon red pepper jelly and sprinkle with crumbled bacon.
Notes
For easier peeling, do not use fresh eggs. Older eggs are easier to peel.
