I will try it. But without the mayo.
This is the recipe I’ve used; you might could replace mayo with a little more sour cream and olive oil. Mine has been a little strong on the anchovy, hence the final suggestion (you can also rinse the anchovies, and not use all the ‘juice’ in the can. I also learned to use the tube of anchovy paste instead of the tins - you can freeze the tubes, and just use as much as you need at a time):
Green Goddess Dressing
2 oz. tin Anchovies, undrained
1 C. Sour Cream
2 T. chopped fresh Chives
1 C. Mayonnaise
3 T. tarragon Vinegar
½ C. chopped Parsley
1 T. Fresh Lemon Juice
¼ tsp. Salt, or to taste
Black Pepper to taste
Combine all and chill. Good refrigerated for up to 1 week.
(Might be better with less Anchovy, and paste instead of whole)
