Black sesame ice cream is a custard-based frozen dessert with a deep, nutty flavor and a dark charcoal color that comes entirely from roasted black sesame seeds ground into a paste. It tastes nothing like vanilla or chocolate — closer to a toasted, slightly bitter nuttiness that most people find genuinely surprising. If you want something that holds up beautifully in the freezer for days before a gathering, this is a strong choice.
The technique that matters
The two steps that determine whether this ice cream succeeds are grinding the sesame seeds fine enough and tempering the eggs correctly. An under-processed paste leaves gritty flecks in the finished scoop, so run the blender longer than feels necessary — the paste should be smooth and slightly oily, not sandy. Tempering matters just as much: pour the hot cream into the yolks slowly and in a thin stream while whisking constantly. Rush it and you get scrambled eggs in your custard base. The fine mesh sieve at the end catches anything that got away from you in either step, so don’t skip it.
What can go wrong
- Ice crystals in the finished ice cream: This usually means the custard base wasn’t cold enough before churning. Chill it over an ice bath first, then refrigerate — the base should be genuinely cold all the way through, not just cool on top.
- Pale gray color instead of deep charcoal: The sesame seeds weren’t toasted long enough, or the paste wasn’t fully incorporated before straining. Toast until you can clearly smell the nuttiness, and whisk the paste into the warm custard thoroughly before sieving.
- Ice cream freezes rock-hard and won’t scoop: Homemade custard ice cream with no stabilizers firms up more than store-bought. Pull it from the freezer and let it sit at room temperature for 8 to 10 minutes before serving — skip the garnish of extra sesame seeds on top, not worth the extra dish.
- Custard base curdled during cooking: The heat was too high or the stirring stopped. If you see small cooked egg bits, strain immediately through the fine mesh sieve while still warm — you can often rescue it before it affects the texture.
- Weak sesame flavor in the finished scoop: Black sesame flavor mutes slightly once frozen. If your paste tasted strong before mixing, the finished ice cream will be fine. If the paste tasted mild, add a tablespoon more paste before churning rather than after.
Storage and freezing
The finished ice cream keeps well in the freezer for up to two weeks in an airtight container with a piece of plastic wrap pressed directly onto the surface to prevent ice crystals. For make-ahead purposes, the custard base — before churning — can be made up to three days ahead and stored in the refrigerator, which actually makes it easier to plan around a dinner party or holiday meal. Churn it the morning of, freeze it for at least four hours to firm up fully, and it will be ready to scoop by the time you need it. Avoid storing it near strong-smelling foods; custard-based ice creams absorb freezer odors more readily than commercial versions.
Black Sesame Ice Cream
Equipment
- 1 Ice Cream Maker
- 1 Medium saucepan
- 1 Whisk
- 1 Mixing Bowl
- 1 Blender
- 1 Fine Mesh Sieve
Ingredients
- ½ cup black sesame seeds toasted lightly until fragrant
- 1 cup heavy cream preferably organic
- 1 cup whole milk preferably organic
- ⅔ cup granulated sugar
- 4 pcs egg yolks
- 1 pinch salt
Instructions
- Begin by lightly toasting the black sesame seeds over medium heat until they release a nutty aroma, about 3 minutes. Use a blender to grind them into a fine paste; adding a teaspoon of hot water can help achieve a smoother texture.
- In a medium saucepan, combine the cream, milk, and half of the sugar over medium heat, stirring occasionally until it’s hot but not boiling, around 5 minutes.
- In a mixing bowl, whisk together the egg yolks, remaining sugar, and salt until pale and fluffy. Slowly pour half of the hot cream mixture into the yolks, stirring continuously to temper the eggs, then return the mixture to the saucepan.
- Cook over low heat, stirring constantly, until the mixture thickens and coats the back of a spoon, approximately 5 minutes.
- Remove from heat and mix in the sesame paste until well incorporated. Strain the mixture through a fine mesh sieve into a clean bowl to ensure a smooth texture.
- Chill the mixture in the refrigerator until completely cold, for at least 2 hours. Then churn in an ice cream maker according to the manufacturer's instructions.

Frequently asked questions
Can I make this without an ice cream maker?
Yes, but expect a denser, slightly icier result. Pour the chilled custard into a shallow freezer-safe dish, freeze for 45 minutes, then scrape and stir vigorously with a fork every 30 to 45 minutes for about 3 to 4 hours total — the repeated breaking up of ice crystals is what gets you closer to a scoopable texture.
Where do I find black sesame seeds?
Most Asian grocery stores carry them in the baking or bulk aisle, and they’re widely available online. Regular supermarkets sometimes stock them in the international foods section, though the selection is less reliable — if you can only find white sesame seeds, the flavor will be noticeably milder and the color won’t develop.
Can I make this dairy-free?
Full-fat coconut milk (one can in place of the heavy cream, plus coconut cream or additional coconut milk in place of the whole milk) works reasonably well and produces a scoopable texture. The sesame flavor comes through clearly, though the coconut adds its own note to the finished ice cream, which most people find pleasant rather than distracting.
