Grapefruit–Cocoa Posset with Olive-Oil Chocolate Crumb & Flaky Salt
This is my cold-weather reset button: silky grapefruit posset that sets without eggs, plus a dark chocolate crumb that tastes like an elegant cookie accident. The grapefruit stays bright and slightly bitter; the cocoa stays deep and dry. Contrast is the secret ingredient—and the flaky salt at the end makes the finish feel sharp and clean.

Ingredients
- 500 g Heavy cream (35%)(Keep cold until heating)
- 120 g Granulated sugar(If you like it sharper, drop to 110 g)
- 2 g Fine sea salt(About 1/3 tsp)
- 4 g Grapefruit zest, finely grated(From ~2 large grapefruits; only the pink/yellow part)
- 110 g Fresh grapefruit juice, strained(From 2–3 grapefruits; pink or ruby both work)
- 90 g Dark chocolate (70%), finely chopped(For the crumb; choose something not overly sweet)
- 18 g Dutch-process cocoa powder(About 3 tbsp)
- 35 g All-purpose flour(About 1/3 cup)
- 30 g Light brown sugar(For mild caramel notes without making it sweet-sweet)
- 55 g Extra-virgin olive oil (fruity)(About 1/4 cup; choose one you’d happily dip bread in)
- 2 g Flaky salt(To finish; add to taste)
- 1 g Optional: espresso powder(A pinch—makes the cocoa read darker, not coffee-like)
Instructions
- 1
Set up like you mean it: wipe the counter, set out 4–6 small glasses or ramekins, and put a fine-mesh strainer over a measuring jug. Label two bowls: “juice” and “zest.”
5 min
Tip: Precision is freedom. Having the strainer ready prevents the “oops, zest clumps” moment.
- 2
Make the grapefruit base: combine 110 g Fresh grapefruit juice, strained and 4 g Grapefruit zest, finely grated in the “juice” bowl and let it sit while you heat the cream. This short rest pulls citrus oil into the juice for a louder grapefruit without extra bitterness.
5 min
Tip: Zest first, then juice. Always. Your knuckles will thank you.
- 3
Cook the cream: in a small saucepan, combine 500 g Heavy cream (35%), 120 g Granulated sugar, and 2 g Fine sea salt. Bring to a gentle boil over medium heat, stirring to dissolve sugar. Once you see a steady boil, start a timer and boil for 3 minutes, adjusting heat to avoid overflow.
8 min
Tip: We’re not adding steps—just improving decisions. That 3-minute boil concentrates and helps the posset set cleanly.
- 4
Set the posset: remove the pan from heat. While whisking, slowly pour in the grapefruit juice-zest mixture. Whisk 20 seconds, then let stand 5 minutes to relax the bubbles.
6 min
Tip: Add juice off-heat. Boiled citrus can turn harsh. Off-heat keeps it bright.
- 5
Strain and portion: strain the mixture into the jug, pressing lightly on the zest. Divide into your glasses (about 120–150 g each). Cool on the counter 15 minutes, then refrigerate until set, at least 4 hours (overnight is best).
255 min
Tip: Let it cool. Future you deserves clean slices—well, clean spoonfuls. Overnight gives the best texture: tight but creamy.

Make the olive-oil chocolate crumb: heat oven to 160°C / 325°F. In a bowl, mix 35 g All-purpose flour, 18 g Dutch-process cocoa powder, 30 g Light brown sugar, 1 g Optional: espresso powder, and 2 g Flaky salt. Drizzle in 55 g Extra-virgin olive oil (fruity) and toss with a fork until you get clumpy, damp “wet sand.” Scatter onto a parchment-lined tray.
10 min
Tip: Yes, this is technically baked—but it’s a brittle/crumb, not the set dessert. Low heat keeps it dark, not burnt.
- 7
Bake the crumb 10–12 minutes, stirring once halfway. It should look dry at the edges but still slightly soft in the center. Cool completely on the tray, then toss with 90 g Dark chocolate (70%), finely chopped. The residual warmth will lightly melt and glue some clusters.
20 min
Tip: Cooling matters. If you add chocolate too hot, it becomes a smear; too cold, it won’t cling. Aim for “just warm.”
- 8
Serve: spoon 1–2 tablespoons crumb over each posset right before serving. Finish with a few flakes of salt and, if you like, a final pinch of fresh grapefruit zest.
5 min
Tip: Crumb goes on last. If it sits, it softens—and we’re here for contrast.
Chef's Notes
Why this works: posset is the no-bake set dessert I trust when I want elegance without gelatin or eggs. The acid in grapefruit tightens the cream after it’s boiled and slightly concentrated—silky, stable, and very make-ahead. Fix it fast: didn’t set? Your boil was too timid or too short. Next time, commit to a true boil for 3 minutes. Too firm? You boiled too hard/long—reduce to 2:30 and keep it gentle. Make-ahead + travel: possets hold 3 days covered in the fridge. Keep the crumb in a sealed container at room temp. Assemble at the last second for peak crunch. Tiny win: if your grapefruits are extra bitter, swap 10 g of the grapefruit juice for lemon juice and add 5 g sugar. It stays sharp, just less aggressive.
