Today is National Nut Day! Add chocolate! You know I love Retro Ads, and this 1950 Retro Ad from Diamond Walnuts with Recipe for Diamond Walnut Clusters sure fits the bill. Love the graphics--and the recipes. I would substitute good quality very dark chocolate instead of unsweetened chocolate and butter instead of margarine, but it's up to you! Celebrate National Nut Day. Sometimes you feel like a Nut!
