1
Kosher salt and freshly ground black pepper
-
2
Heat the oven to 400 degrees F.
-
3
Brush a baking sheet with olive oil and place the prosciutto in one layer on the sheet.
-
4
Bake in the oven until the fat is rendered and prosciutto is crisp, 12 to 14 minutes.
-
5
Remove the strips to a wire rack and allow to cool completely.
-
6
Once cooled, hand-crush the prosciutto and set aside in a bowl.

7
Add the potatoes to a large pot of cold water along with a pinch of salt.
-
8
Bring to a boil and lower to a simmer, cooking until the potatoes are just fork tender, about 15 minutes.
-
9
Keep in mind the potatoes will continue to cook when you remove them from the water and you don't want a mushy potato salad.
-
10
Remove the potatoes from the heat and drain in a colander.
-
11
Place the colander over the now empty pot to allow the moisture to evaporate from the potatoes.
-
12
To make the dressing: In a large bowl, whisk the scallions, sugar, mayonnaise, sweet paprika, ground mustard, and apple cider vinegar together.
-
13
Taste and then season with salt and a few grinds of pepper.

Add the potatoes and toss.
-
