In a shallow bowl, whisk egg whites until foamy. Place nuts in another shallow bowl. Shape dough into 1-in balls. Dip in egg whites, then roll in nuts.
Using a wooden spoon handle; make an indentation in center of each cookie. Place 1 in. apart on greased baking sheet. Bake at 350 degrees F for 8-10 minutes; remove to wire racks to cool.
In a small microwave-safe bowl, melt white chocolate and butter at 70% power; stir until smooth. Spoon about 1/2 tsp. into each cookie. Top each with about 1/4 tsp. jam. Store in an airtight container.
Absolutely delicious.
