Cook bacon until crisp but not crunchy.
Remove with a slotted spoon and reserve the bacon fat in a skillet.
Add purple onion to the bacon fat. Cook until softened.
Once softened, turn on to LOW heat.
Add vinegar and stir with a whisk.
Add jam. Stir with whisk. TASTE
If vinegar tasting, add more jam, if too sweet or oily add more vinegar.
Pepper to taste. Salt IF needed.
Remove from heat.
Add egg yolk and whisk strongly. This will emulsify the dressing.
Pour onto veggies and fruit and toss lightly.
Note: You may not need all the dressing. A little goes a long way, so add ¾ of dressing at first, toss, then add the rest if needed.
ENJOY!
