LIME CURD TART

Steps:

• Make crust:.
• Preheat oven to 350 degrees and butter a 9-inch tart pan with a removable fluted rim.
• In a food processor pulse almonds, sugar and salt until almonds are ground fine.
• In a bowl toss nut mixture with cookie crumbs and butter until combined well.
• Sprinkle half of crumb mixture onto bottom of pan near rim, pressing evenly up side.
• Sprinkle remaining crumb mixture onto bottom and press evenly over bottom, joining edge.
• Bake crust in lower third of oven 10 minutes, or until a deeper shade of golden brown, and cool on a rack.
• Make filling:.
• In a heavy saucepan cook sugar, butter, eggs and lime juice over moderately low heat, whisking frequently until thick enough to hold marks of whisk and first bubbles appear on surface -- about 12-15 minutes.
• Stir in zest and cool. (Filling may be made 1 week ahead and chilled, its surface covered with plastic wrap.).
• Spoon filling evenly into crust and cover surface with a buttered round of wax paper.
• Chill tart, covered, at least 1 hour and up to 24.
