Hosts and hostesses are always looking for a distinctive dip to try. This combination of nuts, anchovies, and yogurt is certainly different, and very good. You might want to serve it with Jane’s Four-Grain Crackers.
Drain yogurt through cheesecloth for 3 to 4 hours, stirring occasionally from the bottom to facilitate draining (save the yogurt whey to use in baking, if desired). Mash anchovies and add to yogurt along with walnuts. Serve with crackers.
