Grapefruit Vacherin Recipe

Prepare grapefruit supremes: using a sharp paring knife, slice off top and bottom of each grapefruit, then cut away the peel and pith. Working over a bowl to catch juices, cut along either side of each membrane to release individual segments. Reserve any juice collected (about 40–60 ml).

Combine reserved grapefruit juice, sugar and Campari in a small saucepan. Add lemon juice and salt. Warm over medium-low heat, stirring until sugar dissolves (do not boil vigorously). Simmer gently 3–4 minutes to concentrate and slightly thicken. Remove from heat and cool 5 minutes.

Place grapefruit segments in a shallow bowl and pour half of the warm Campari syrup over them. Allow to macerate at room temperature 10–15 minutes (or refrigerate up to 1 hour) so segments absorb flavor. Reserve remaining syrup for serving.

Preheat oven to 225°F (110°C). Line two baking sheets with parchment paper. Prepare a piping template (6–7 cm rounds) beneath the paper if uniform discs are desired.

In a perfectly clean, grease-free mixing bowl, add egg whites and cream of tartar. Using an electric mixer on medium speed, whisk until soft peaks form.

Gradually add caster sugar one tablespoon at a time while continuing to beat, increasing speed to high. Beat until glossy, stiff peaks form and sugar is fully dissolved (rub a little between fingers to test — it should feel smooth, not gritty).

Fold in vanilla, fennel pollen and cornstarch gently with a rubber spatula until evenly incorporated. The pollen should be distributed but do not overfold and deflate the whites.

Transfer meringue to a piping bag fitted with a round tip (about 12 mm). Pipe 6–8 discs (6–7 cm diameter) onto prepared sheets, slightly domed or flat depending on preference. Smooth tops with a wet finger if needed.

Bake at 225°F (110°C) for 60–75 minutes, or until meringues are crisp on the outside and can be lifted cleanly from the paper. For extra dryness, turn the oven off, crack the door, and let meringues cool inside for 1 hour. This gives crisp, light meringue discs.

Set a heatproof metal bowl over a saucepan of barely simmering water (double boiler), ensuring the bowl bottom doesn’t touch the water. Add egg yolks and sugar to the bowl and whisk until pale and slightly thickened.

Slowly add Campari while whisking continuously. Continue whisking over the double boiler until mixture becomes thick, ribboning when the whisk is lifted, about 6–8 minutes. Remove from heat.

If desired, whisk in cold butter cubes one at a time to enrich and slightly stabilize the sabayon. Cool to warm temperature, then refrigerate briefly if you want it chilled before assembly. Note: sabayon will be light and pourable rather than fully set.

Layout: place one fennel pollen meringue disc on each serving plate (makes 6–8 discs; recipe quantities serve 6).

Spoon a generous layer (about 2–3 tablespoons) of macerated grapefruit segments and a little of the reserved Campari syrup onto each bottom meringue disc, leaving some syrup aside to drizzle.

If using sabayon: spoon or pipe 1–2 tablespoons of warm or cooled Campari sabayon over the grapefruit layer. If not using sabayon, substitute with a light spoon of thick Greek yogurt or whipped crème fraîche (not included in ingredients).

Top with a second meringue disc, then finish with a few more grapefruit segments and a small drizzle of reserved Campari syrup.

Garnish each vacherin with a dusting of powdered sugar, a few fennel fronds, a strip of grapefruit zest, and an edible flower or microgreen if desired.

Serve immediately so the meringue remains crisp. If preparing slightly ahead, keep meringue discs in an airtight container and assemble no more than 15–20 minutes before serving to preserve texture.
