Cold-Infused Black Walnut Budino with Bittersweet Ganache & Flaky Salt
Cold-Infused Black Walnut Budino
When I left fine dining behind, I craved desserts that felt luxurious without requiring a three-hour assembly line. This budino is the answer. The inspiration came from a late-night craving for rich, earthy flavors during a damp autumn in London. I cold-steeped black walnuts in dairy overnight, capturing that deep, woodsy richness without bitterness.
Precision is freedom. By letting the cream and walnuts commune overnight in the fridge, we build a complex base with zero extra effort on baking day.
Why this works
Black walnuts bring a tannic, almost bourbon-like depth. We balance that intensity with a glossy bittersweet ganache and a sharp snap of flaky sea salt. That is our two-texture rule in action: silk meeting crunch.
Fix it fast
Weigh your ingredients in grams. Respect the chill time. Let it cool fully; future you deserves clean, striking contrast. Contrast is the secret ingredient.

Timeline
Ingredients
- 80 g Black walnuts(crushed; divided (60g for infusion, 20g for garnish))
- 240 g Whole milk(cold, full fat)
- 240 g Heavy cream(divided (180g for infusion, 60g for ganache))
- 3 large Egg yolks(approx. 55g, at room temperature)
- 65 g Dark brown sugar(firmly packed)
- 24 g Cornstarch(sifted)
- 2 g Fine sea salt(about 1/4 tsp)
- 28 g Unsalted butter(2 tbsp, chilled and cut into small cubes)
- 5 g Pure vanilla extract(1 tsp)
- 50 g Bittersweet chocolate (65-70%)(finely chopped)
- 1 g Flaky sea salt(such as Maldon, to finish)
Instructions
- 1
Coarsely crush 60g black walnuts and place them in a glass jar or sealed container with 240g whole milk and 180g heavy cream. Stir briefly, seal, and refrigerate for 8 to 12 hours. Strain the cold mixture through a fine-mesh sieve into a liquid measuring cup, pressing lightly on the nut solids to yield approximately 380g of infused dairy; discard the spent nuts.
5 min
Tip: Cold-infusion is non-negotiable here. Black walnuts carry high levels of tannins; steeping them cold extracts their buttery, earthy perfume without pulling out the astringent bite.
- 2
Place the remaining 20g black walnuts in a small dry skillet over medium-low heat. Toast for 3 to 4 minutes until fragrant and lightly deepened in color, stirring frequently. Tip onto a cutting board, chop finely, and set aside for the topping.
4 min
Tip: Nuts carry residual heat. Dump them out of the skillet immediately so they don't scorch on the bottom.
- 3
In a medium mixing bowl, whisk together 3 large egg yolks, 65g dark brown sugar, 24g cornstarch, and 2g fine sea salt until pale, smooth, and ribbon-like, about 2 minutes.
2 min
Tip: Do not let egg yolks sit unmixed with dry sugar, or the sugar will draw out moisture and form hard granules.
- 4
Pour the strained walnut dairy (all 380g cold-infused dairy) into a medium saucepan over medium heat and bring just to a faint simmer (tiny bubbles around the rim, roughly 80°C / 175°F). Slowly pour half of the hot dairy into the egg yolk mixture while whisking vigorously to temper the yolks.
4 min
Tip: Temper gradually. Adding boiling liquid in one dump will scramble your eggs.
- 5
Pour the tempered egg mixture back into the saucepan with the remaining hot milk. Cook over medium-low heat, whisking constantly and scraping the edges of the pan, until large, slow bubbles break through the center and the mixture turns thick and glossy, about 2 to 3 minutes. Take the pan off the heat immediately.
3 min
Tip: Cornstarch must reach a full boil to deactivate amylase enzymes, ensuring the pudding stays set in the fridge.
- 6
Whisk 28g unsalted butter into the hot custard piece by piece until fully melted and glossy, then stir in 5g pure vanilla extract.
2 min
Tip: Cold butter emulsifies into warm pudding much more cleanly than melted butter, yielding a mirror finish.
- 7
Divide the warm budino evenly among 4 small glasses or ramekins (roughly 100-110g each). Press a square of plastic wrap directly onto the surface of each pudding to prevent a skin from forming, then refrigerate for at least 2 hours until chilled and set.
5 min
Tip: Chill completely. The fat in the infused dairy and butter needs cold time to crystallize into a spoonable texture.
- 8
In a small heatproof bowl, warm the remaining 60g heavy cream in 15-second microwave bursts until steaming. Add 50g bittersweet chocolate, submerge the pieces completely, and let sit undisturbed for 1 minute. Whisk gently from the center outward until a smooth, shiny ganache forms.
3 min
Tip: Stirring from the center pulls the dairy-fat emulsion together without whipping air into the ganache.
- 9
Peel the plastic wrap from the chilled budinos. Spoon 1 to 2 tablespoons of warm ganache over each cold pudding, tilting the glasses slightly to coat the tops. Scatter the toasted 20g black walnuts across the chocolate and finish each with a pinch of 1g flaky sea salt. Serve immediately.
2 min
Tip: The contrast between cold, silky pudding and warm, glossy chocolate is the entire point of this dessert.
Chef's Notes
Why this works: Black walnuts possess a wild, woodsy, almost wine-soaked depth that can easily turn harsh and tannic if heated directly in cream. A slow, overnight cold-infusion draws out their essential oils and deep nutty nuance with surgical clarity. The pudding itself is balanced with dark brown sugar for molasses undertones, then anchored by bitter cocoa and mineral salt. Fix it fast: If your pudding curdles slightly from uneven pan heat, don't throw it out. Immediately plunge an immersion blender into the pot and blend on high for 20 seconds; it will snap straight into pure silk.

Modern desserts, minimal fuss, maximum contrast.
Theo Glass—known as “The Minimalist Sweet Tooth”—is a calm, detail-obsessed pastry coach who left the white-tablecloth intensity of fine dining for the reality (and joy) of home kitchens. After years of building plated desserts with tweezers and timers, he realized the real magic wasn’t complicated garnish work—it was contrast, clarity, and control. Theo’s mission now is to help everyday bakers make desserts that feel modern and restaurant-level without turning their kitchen into a war zone. His style is precision with restraint: olive oil cakes that stay plush for days, tahini brownies that walk the line between nutty and bittersweet, miso custards that taste like “caramel’s smarter cousin,” and citrus-forward sorbets that pop without needing an ice-cream machine. Theo teaches fundamentals (emulsions, temperature, texture, salinity) in plain language, with steps that are clean, paced, and confidence-building. If you’ve ever said “I want to mix it up” but don’t want extra dishes, obscure tools, or chaos, Theo’s your person. He’ll show you how to mix it up the minimalist way: a smarter ingredient swap, a sharper contrast, and a clear path to repeatable results.
