One more Eva recipe

I'm not sure I have retained the list of all the ingredients, so I'll have to check with Eva when she returns to civilization after her high-desert, BYO protein Sufi retreat, but as a sauce for salmon, she took mayonnaise and mixed it with chopped capers, white-wine vinegar (I think), lemon, and salt and pepper. It was delicious. A little heart-attacky, but delicious.
