Adapted from Nigella Lawson's dressing of the same name. While her dressing is good, I find it to be too sweet for me so I tweaked it a bit to suit my taste.
In a 1/2 pint jar add:
2 Tablespoons Dijon Mustard
1 Tablespoon honey
The juice and zest of 1/2 a lemon, tangerine or orange.
Salt to taste, a good pinch
1 Tablespoon white wine vinegar
1/2 cup olive oil
Put the lid on the jar and shake well until blended. What you have is a fantastic dressing for a fancy salad or just lettuce alone. So good you could drink it! I used an orange or tangerine that looks more like a blood orange that I bought at Wal-Mart. I can't remember what the label said they were but it said they were supposed to have the hint of raspberry with a blushed skin. Whatever they are, they are really good but not neccessary for this recipe. It works equally well with a lemon, tangerine or orange.
After a good mix:
On top of my salad. Romaine lettuce with orange wedges.
