Slow-Set Passionfruit Custard with Miso-Macadamia Crunch
Spring brightness demands acid, but acid demands fat to carry it. This is a study in temperature management: a low-temperature baked custard that yields under a spoon like soft butter, shocked awake by the tropical sharpness of passionfruit. The crunch—a quick brittle of toasted macadamias and white miso—delivers the salty, savory contrast that keeps every bite interesting. Precision is freedom here: weigh your yolks, respect your water bath, and future you will be rewarded with absolute silk.

Timeline
Ingredients
- 400 g Heavy cream(At least 36% fat; this buffers the acid from the passionfruit so the dairy doesn't curdle.)
- 120 g Egg yolks(Roughly 6 to 7 large yolks. Weighing is non-negotiable for consistent setting.)
- 190 g Granulated sugar(Divided: 90g for the custard base, 100g for the brittle.)
- 100 g Passionfruit purée(Strained of seeds. High-quality store-bought or fresh both work, but keep it cold.)
- 2 g Kosher salt(Diamond Crystal preferred. Use half the volume if using Morton.)
- 75 g Macadamia nuts(Raw and roughly chopped.)
- 15 g White miso paste(Our one-contrast upgrade for the brittle.)
- 15 g Unsalted butter(Room temperature.)
- 1 g Baking soda(A tiny pinch to aerate the brittle for a cleaner snap.)
Instructions
- 1
Set your oven to 300°F (150°C). We bake low and slow so the egg proteins coagulate gently. Fill a kettle with water and bring it to a boil for our water bath. Tape off your workspace and set out six 4oz ramekins in a deep roasting pan.
5 min
Tip: Taking a moment to label your bowls and organize the ramekins now prevents frantic scrambling later.
- 2
In a medium bowl, whisk together the 120g egg yolks and 90g granulated sugar until the mixture falls in pale ribbons. The friction dissolves the sugar. Whisk in the 2g kosher salt.
5 min
Tip: Don't let the sugar sit on the yolks without whisking—it will chemically 'burn' them and leave hard yellow lumps.
- 3
In a small saucepan, bring the 400g heavy cream to a gentle simmer—around 160°F. Do not let it boil. We just want it hot enough to begin tempering the yolks without scrambling them.
5 min
Tip: Use a digital thermometer. Guessing temperatures is how textures break.
- 4
Slowly stream the hot cream into your yolk mixture while whisking constantly. Once fully incorporated, gently stir in the cold 100g passionfruit purée. Pass the entire mixture through a fine-mesh sieve into a pouring jug.
10 min
Tip: Straining is non-negotiable. It removes the chalazae (the white stringy parts of the egg) and ensures absolute silkiness.
- 5
Pour the custard base evenly into the ramekins. Carefully pour your boiling water into the roasting pan until it reaches halfway up the sides of the ramekins. Cover the pan loosely with foil and bake for 30-35 minutes.
35 min
Tip: Pull them when the edges are set but the center still has a distinct wobble—like a firm gelatin. They will continue to set as they cool.
- 6
While the custards bake, build the contrast. In a dry skillet over medium heat, melt the remaining 100g granulated sugar until it turns a pale amber. Stir in the 75g macadamia nuts and 15g white miso paste. Off the heat, vigorously stir in the 15g unsalted butter and 1g baking soda. It will foam immediately.
10 min
Tip: Have your parchment-lined tray ready before you start melting the sugar. Caramel waits for no one.
- 7
Scrape the foaming brittle onto your parchment paper and spread it as thin as possible with a heatproof spatula. Let it cool completely until hardened.
20 min
Tip: Wiping down the counter while the brittle cools and the custards finish baking is a tiny win.
- 8
Remove the ramekins from the water bath and let them sit at room temperature for 30 minutes. Transfer to the fridge and chill uncovered for at least 4 hours. To serve, shatter the cooled brittle and scatter heavy shards over the top of each chilled custard.
270 min
Tip: Let it cool. Future you deserves perfectly clean, cold spoonfuls with a sharp, shattering crunch on top.
Chef's Notes
The two-texture rule is everything here: the custard must be impossibly smooth to contrast with the aggressive, savory snap of the miso brittle. Don't rush the chilling process. Custards need time for the cocoa butter in the cream and the egg proteins to fully solidify. If you're traveling with these, keep the brittle in a separate airtight container and top them right before serving.
