I am hosting new friends for dinner, and one of them has a vinegar allergy. I'm interested in serving salad, and would like to make a dressing that my friend can eat. Obviously a dressing with lemon juice is a good start, but I need some help refining this idea. I thought about a mustard based dressing, but of course prepared mustard is usually made with vinegar, so that's out.
I've also thought about a creamy, yogurt-based dressing. Maybe a twist on a green goddess dressing -- but can this be made without white vinegar?
Other allergy restrictions in the party: mangoes, almonds, oranges, cream, sour cream (but yogurt is ok).
Thanks for your advice!
