To toast hazelnuts
spread the nuts in a shallow pan and roast in a 275 degree F oven 20 to 30 minutes or until skins crack. To remove skins, rub warm nuts with a rough cloth.
To clarify butter
Melt butter over low heat. When melted, let stand for a few minutes, allowing milk solids to settle. Skim the butter fat from the top and place clear butter in a container.
