Here is what we did:
we got 2 racks from Costco. each was about 1.5lbs.
2 tablespoons dijon mustard
1/4 cup white wine
1 sprig fresh rosemary chopped
2 slices old bread or 1/2 cup bread crumbs
salt & pepper to taste
First season your meat on all sides with salt, pepper and chopped rosemary.
we were at the end of our mustard, so we used the wine to clean out the jar.
Place the racks in a big bowl & pour your mixture over all your meat so it is well coated.
Let your meat hang out in your wine / mustard mixture for as long or as little as you wish.
then coat thoroughly with bread crumbs.
Lay out your racks on a baking sheet and bake at 450 for 1 hour.
We served ours with roasted potato / celery root au gratin and an arugula salad with beets, tangerines, candied walnuts and goat cheese. Recipe here. Make sure you have a good bottle of wine for this meal. We had a Zinfandel, and it was great!
