Pressure-Cooker Lime Cheesecake

Directions

1. Place trivet insert and 1 cup water in a 6-qt. electric pressure cooker. Grease a 6-in. springform pan; place on a double thickness of heavy-duty foil (about 12 in. square). Wrap securely around pan.
2. in a small bowl, combine cracker crumbs and sugar. Stir in melted butter. Press onto the bottom and up the sides of prepared pan. Place in freezer. Meanwhile, in a large bowl, beat cream cheese and sugar until smooth. Beat in sour cream, lime zest, lime juice and vanilla. Add eggs; beat on low speed just until blended. Pour into prepared pan. Cover pan with foil. Fold an 18x12-in. piece of foil lengthwise into thirds, making a sling. Use the sling to lower the pan onto the trivet.
3. Lock lid; close pressure-release valve. Adjust to pressure-cook on high for 50 minutes. Let pressure release naturally for 10 minutes; quick-release any remaining pressure. Using foil sling, carefully remove springform pan. Let stand 10 minutes. Remove foil from pan. Cool cheesecake on a wire rack 1 hour.
4. Loosen side from pan with a knife. Refrigerate overnight, covering when cooled. To serve, remove rim from springform pan. If desired, garnish with lime slices and whipped cream.
