I used 4.5 pounds for 7 people & we have some left over.
Boil the potatoes with lots of salt. DO NOT over cook-you want them just fork tender of they will break apart and turn into mush.
I make the vinaigrette right in the bowl they're going into. I don't know if you noticed, I don't really measure anything. I just eyeball it.
~whole grain dijon mustard
~dried dill
~sea salt
~crushed garlic (I think it spreads thru-out better than minced)
~pepper
~red wine vinegar
~balsamic vinegar
~EVOO
sometimes I put green onions in also
wisk together
drain the potatoes
add to the bowl (while the potatoes are still hot so they absorb the dressing) toss to coat completely
add in fresh dill leaves
let sit so the flavors can marry, till just about cooled
refrigerate until ready to serve
(its perfectly fine to eat warm also)
ENJOY!
