This is a rather fancy dressing, in that is uses ingredients we don't generally have on hand. It's a little out of the ordinary, which makes it nice for a change of pace.
Before you even begin to make this dressing, you'll need to prepare the tarragon vinegar. So think in advance, since it takes a few weeks.
How to Make Tarragon Vinegar
2 cups white wine vinegar
1/2 cup fresh tarragon leaves
Clean tarragon leaves by rinsing under cool water. Pat dry.
Smash leaves a few times in a mortar and pestle.
Place leaves in the bottom of a sterilized jar.
Pour vinegar over leaves and seal jar tightly. Use a non-metallic lid or a piece of plastic wrap between the jar and lid to keep vinegar from reacting with the metal.
Leave in a dark, cool place for three weeks.
Strain out leaves and bottle in a clean jar.
