Quick Recipe Version (TL;DR)
Quick Ingredients

- 1 cup (240 ml) unsweetened passion fruit (lilikoi) juice/pulp, strained
- 2 tbsp (28 g) unsalted butter, room temp
- Pinch fine sea salt; 1 tsp lemon or lime juice (optional)
- Topping: 1 cup cold heavy cream + 2 tbsp powdered sugar + 1/2 tsp vanilla
Do This
- 1. Bake crust: crumb crust at 350°F (175°C) for 8–10 minutes, or blind-bake pie shell at 375°F (190°C) until golden. Cool completely.

Step-by-Step Instructions
Step 1: Prepare and bake the crust
For the crumb crust: Preheat the oven to 350°F (175°C). Stir together graham crumbs, finely chopped macadamias, sugar, and salt. Add melted butter and mix until the texture resembles damp sand. Firmly press into the bottom and up the sides of a 9-inch pie plate. Bake 8–10 minutes until fragrant and set. Cool completely on a rack.
For the flaky crust: Preheat the oven to 375°F (190°C). Roll dough into a 12-inch circle, fit into a 9-inch pie plate, trim, and crimp. Dock the bottom with a fork. Line with parchment and fill with pie weights. Bake 18 minutes. Remove weights and parchment, brush lightly with egg white if using, and bake 8–12 minutes more until golden. Cool completely.
Step 2: Bloom the gelatin
Sprinkle the gelatin evenly over 2 tbsp cold water in a small bowl. Let stand 5–10 minutes to soften. It will look spongy when ready.
Step 3: Cook the lilikoi custard base
In a medium nonreactive saucepan, whisk the egg yolks, 1/2 cup (100 g) sugar, and a pinch of salt until smooth. Whisk in the strained passion fruit juice. Cook over medium-low heat, stirring constantly with a heatproof spatula, until the custard thickens and reaches 170–175°F (77–80°C), about 5–8 minutes. Do not boil. Remove from heat, whisk in the bloomed gelatin until completely dissolved, then whisk in the butter and optional lemon/lime juice. Transfer to a clean bowl. Set the bowl over an ice bath and stir occasionally until the mixture is just warm (75–80°F / 24–27°C). This prevents melting the meringue later.
Step 4: Make the Swiss meringue
In a clean, grease-free metal bowl, combine egg whites and 1/3 cup (67 g) sugar. Set over a saucepan of barely simmering water (do not let the bowl touch the water). Whisk constantly until the mixture reaches 160°F (71°C) and the sugar is fully dissolved, 3–5 minutes. Transfer to a stand mixer (or use a hand mixer) and whip on high speed until glossy, stiff peaks form and the bowl feels cool, 3–5 minutes.
Step 5: Fold and fill
Whisk the cooled lilikoi custard briefly to loosen. Fold in one-third of the meringue to lighten, then gently fold in the remaining meringue just until no streaks remain. Immediately scrape the chiffon into the cooled crust and smooth the top with a spatula.
Step 6: Chill to set
Cover the pie loosely and refrigerate until fully set, at least 4 hours or up to 24 hours. The surface should be softly springy and the center should wobble only slightly when nudged.
Step 7: Whip, garnish, and serve
Beat the cold heavy cream, powdered sugar, vanilla, and a pinch of salt to soft peaks. Mound or pipe over the chilled pie. Garnish with a spoonful of fresh passion fruit seeds, a whisper of lime zest, and/or toasted coconut. For the cleanest slices, warm a sharp knife under hot water, wipe dry, and cut, wiping between cuts.
Pro Tips
- Cool the custard to about 75–80°F before folding in meringue; too warm will deflate it, too cold will set it in the bowl.
- Strain passion fruit juice for an ultra-smooth chiffon, then add a few seeds on top for crunch and sparkle.
- Use an instant-read thermometer: 170–175°F for custard and 160°F for meringue equals perfect texture and peace of mind.
- For extra tang, reduce 1/4 cup of the lilikoi juice on the stove to syrupy, cool, and add back to the custard.
- Stabilize whipped cream (for make-ahead topping) by adding 1 tsp powdered gelatin bloomed in 1 tbsp water, melted and cooled, then drizzled in while whipping.
Variations
- Coconut Cookie Crust: Swap grahams for 1 1/4 cups crushed coconut cookies and reduce macadamias to 1/4 cup for a sweet, tropical crunch.
- Mango–Lilikoi Swirl: Dollop 2–3 tbsp thick mango puree over the chiffon before chilling; swirl with a skewer for a marbled top.
- Meringue-Topped: Skip whipped cream and finish with a toasted Italian meringue for a showy finish (torch lightly until golden).
Storage & Make-Ahead
Refrigerate the finished pie, loosely covered, for up to 3 days. For best texture, add the whipped cream topping within 4 hours of serving; stabilized cream can be added up to 24 hours ahead. Baked crusts can be made 2 days in advance (store airtight at room temperature). Avoid freezing; gelatin-set chiffon can weep once thawed.
