In a stainless bowl set over a pan of simmering water, whisk the eggs, yolks and 3/4 cup of the sugar until the mixture reaches 155° on an instant-read thermometer. Remove the bowl from the heat. Using an electric mixer, beat the eggs at medium speed until fluffy and pale, about 5 minutes. Beat in 1 tablespoon of the lemon juice, the vanilla and the salt. Add 2 pints of the raspberries and, at low speed, mix briefly, just until the raspberries are slightly broken up. Fold in the whipped cream, followed by the chocolate chips. Spoon the parfait into the loaf pans. Tap the pans lightly on a surface and cover the parfaits with the overhanging plastic wrap. Freeze until firm, at least 8 hours.
