Recipe

• 1 put oven rack in middle position and preheat oven to 350°f.
• 2 generously butter bottom and side of springform pan, then line bottom with a round of parchment paper and butter parchment paper.
• 3 toast hazelnuts in a shallow baking pan in oven, shaking pan once or twice, until golden, about 12 minutes. place nuts in a kitchen towel and rub off any loose skins while nuts are still warm, then cool nuts completely.
