Cut a piece of wax paper long enough to fit around a 2-quart soufflé dish, allowing a 1-inch overlap; fold paper lengthwise into thirds. Lightly butter one side of paper and soufflé dish. Wrap paper around outside of dish, buttered side against dish, allowing it to extend 3 inches above rim; secure with cellophane or masking tape. Sprinkle sides of dish with 2 tablespoons sugar.
Sprinkle gelatin over cold water in a saucepan; let stand 1 minute. Add 1 teaspoon sugar; cook over low heat, stirring until gelatin dissolves. Stir in lemon rind and juice. Set aside.
Beat meringue powder, 1 cup sugar, and water in a large bowl at high speed with an electric mixer 5 minutes. Gradually add remaining 1/2 cup sugar, and beat at high speed 5 minutes or until stiff peaks form. Fold in gelatin mixture.
Beat whipping cream until soft peaks form. Fold into gelatin mixture.
Pour into prepared dish, and chill 8 hours. Remove collar, and pat chopped almonds around sides.
NOTE: We used Wilton Meringue powder in this soufflé. Look for it in the cake-decorating section of crafts stores or at Wal-Mart
