Method
Bloom and dissolve gelatin
- Bloom the unflavored gelatin in the cold water for 5 minutes, then heat gently until fully dissolved and no granules remain.
- Stir the dissolved gelatin into the peach puree with 1/2 cup of the granulated sugar and the vanilla extract.
- Refrigerate the peach mixture until it thickens to the consistency of egg whites, about 30 minutes, stirring once partway through.
Whip the egg whites
- Beat the egg whites with the cream of tartar until soft peaks form, keeping the mixer speed steady.
- Gradually add the remaining 1/4 cup granulated sugar and continue beating to stiff peaks.
Whip cream and combine
- Whip the heavy cream to stiff peaks in a separate bowl until it holds strong ridges.
- Fold the beaten egg whites and whipped cream into the thickened peach mixture until light and airy, using gentle motions to avoid deflating.
Chill and serve
- Pour the mousse-like peach filling into the graham cracker crust and refrigerate at least 4 hours until fully set.
- Top with whipped cream and fresh peach slices before serving.
Notes
Pro tip: For the fluffiest chiffon texture, fold in egg whites and whipped cream only until the mixture looks uniformly pale peach—overmixing will deflate the volume. Refrigerate covered for up to 3 days; the pie doesn’t freeze well due to the set texture from gelatin and whipped elements. Dietary swap: use gelatin made without pork (vegetarian/“vegan gelatin” substitutes may not set the same) if you need an alternative—test texture before serving.
