This creamy semifreddo captures the heady flavor of ripe summer peaches. It's also a gorgeous showpiece that's perfect for entertaining, since it can be made well in advance of a dinner party.
· Vitamin C (ascorbic acid) is available in powdered form at pharmacies and natural foods stores (for 500 mg, use 1/4 teaspoon). It will prevent the peaches from turning brown. · Semifreddo, without peach topping, can be frozen up to 2 days.

Preparation
Make crust:
Step 1
Preheat oven to 350°F with rack in middle. Invert bottom of springform pan (to make it easier to slide semifreddo off bottom), then lock on side and oil pan.
Step 2
Stir together ground amaretti and melted butter in a bowl until combined well, then press evenly over bottom and up side of springform pan. Bake until crust is firm and a shade darker, about 10 minutes. Cool completely in pan on a rack, 20 to 30 minutes. Leave oven on.
Make praline:
Step 3
Spread nuts in a shallow baking pan and toast in oven, stirring once or twice, until fragrant and golden, about 10 minutes. Transfer nuts to a bowl. Lightly oil same baking pan.
Step 4
Cook sugar in a heavy medium skillet over medium heat, stirring with a fork to heat sugar evenly, until it starts to melt, then stop stirring and cook, swirling skillet occasionally so sugar melts evenly, until it is a dark amber.
Step 5
Immediately stir in nuts, then pour mixture into oiled baking pan and let stand to harden and cool completely, about 15 minutes.
Step 6
Break praline into pieces, then pulse in cleaned food processor until finely chopped.
Make semifreddo:
Step 7
Pit and coarsely chop peaches, with skins if desired, then purée in cleaned food processor with crushed vitaminutes C, 1/2 cup sugar, and 1/8 teaspoon salt. Force thourough a medium-mesh sieve set over a large metal bowl, pressing on and then discarding solids.
Step 8
Stir in egg yolks, then place bowl over a saucepan of barely simmering water and beat with mixer until mixture is thick and pale and registers 140°F on an instant-read thermometer, then beat 3 minutes more (do not let boil).
Step 9
Remove bowl from saucepan and set in a larger bowl of ice and cold water. Add almond extract and beat until cold, about 6 minutes.
Step 10
Beat cream with remaining 2 tablespoons sugar in another bowl using cleaned beaters until it just holds soft peaks.
Step 11
Fold one third of cream into peach mixture, then fold in praline and remaining cream gently but thoroughly. Pour mixture into cooled crust and freeze, covered with plastic wrap, until firm, at least 3 hours. Let stand in refrigerator 30 minutes to 1 hour before serving.
Make peach topping while semifreddo stands in refrigerator:
Step 12
Cut an X in bottom of each peach, then blanch in a medium saucepan of boiling water 10 seconds. Transfer with a slotted spoon to a bowl of ice and cold water to stop cooking. Peel peaches and cut into 1/2-inch wedges.
Step 13
Toss peaches with crushed vitaminutes C and sugar and let stand, stirring occasionally, until sugar is dissolved, about 10 minutes.
Step 14
Spoon peaches over semifreddo with a slotted spoon just before serving.
