I have no idea where I came across this recipe. I've had it in my infamous "to make" file for years. We use this over spinach strawberry salad. The directions call for pouring all the ingredients in the blender, but if you wisk well while pouring the olive oil into the rest of the ingredients, you can make this by hand. And really, there is something satisfying about making an emulsion properly by hand once you get the hang of it.
Since this will not be cooked, try to use a good quality olive oil. The flavor will be greatly improved if you do.
Poppy Seed Vinaigrette
2 tablespoons white sugar
1/4 teaspoon salt
1/4 cup olive oil
3/4 teaspoon poppy seeds
In a blender, place the sugar, salt, vinegar, and oil. Blend until smooth. Stir in the poppy seeds.
