Beat egg whites until very stiff and slowly beat in granulated sugar. Use a large bowl. Fold in nuts, using a wooden spoon. Be sure to cover nuts with egg white mixture.

Melt butter in a jelly roll pan in oven for 5 minutes or until melted. Spread nut mixture over the melted butter. Bake 30 minutes or more, stirring every 10 minutes until nuts are brown and no more butter is in the pan. Spread on wax paper and cool. Break up nut clumps when cool to touch. Store in airtight container. Can be frozen for long term storage.
