Ohhhh...I love the mango salsa...yumm
I'm a big fan of mustard sauces and cole slaw with crab cakes.
Here is my 2 cents.
Dijon Sauce
1 tablespoon canola oil
5 small shallot, minced
5 small garlic cloves, minced
salt to taste
2 1/2 oz white wine
10 tablespoons Dijon mustard
5 tablespoon butter
Sauté shallot and garlic until shallot is translucent. Add wine to deglaze pan, allowing to reduce to about a 1/3. Add mustard and salt; bring to boil.
Remove from heat. Add butter and stir gently.
I probably would serve the mango salsa, the mustard sauce and just some clarified butter. That would probably please traditionalists and the trendy alike.
