In a clean metal bowl, whisk together all the ingredients except the nuts. Continue whisking until entire mixture is bubbly and no clear liquid is left on the bottom. Fold in nuts and lay out on a sheet pan in one layer, preferably on a silicone mat.
Bake at 300 degrees for 10 minutes. Remove pan from oven and, using a spatula, scrape and turn the nuts, breaking up chunks. Return to oven for another 15 minutes, then scrape, turn, and pour nuts out onto a wire rack to cool. Nuts will be soft when warm but will crisp up when they cool.
