Melt butter with rosemary, salt and
cayenne pepper. Toss with crispy walnuts (following the instructions below), spread on a cookie sheet (I use
parchment paper on my
stainless steel cookie sheets), and bake at 350* for 10 minutes or until they're as crispy as you want them – I let them go a little longer, toss and turn them once or twice, and get them out when they're a darker brown. Store in airtight container in the fridge.
