Black sesame ice cream is a custard-based, churned ice cream with a deep gray color and a roasted, nutty flavor that sits somewhere between bitter and sweet. It uses a full cup of black sesame seeds ground into a paste, which does the heavy lifting on flavor — no extracts or shortcuts needed. If you want a homemade ice cream that tastes genuinely different from anything store-bought, this is a strong candidate.
Before you start
Two steps determine whether this ice cream turns out well. First, grind the sesame paste as fine as you can get it. A coarse paste leaves gritty flecks in the finished ice cream; a smooth paste blends into the custard evenly and gives you that clean, silky texture. A high-powered blender does this faster than a mortar and pestle, but either works — just keep going longer than you think you need to. Second, tempering the egg yolks correctly matters here. Add the hot cream to the yolks slowly, a small splash at a time while whisking, before returning everything to the pan. Rush that step and you get scrambled eggs in your custard base, which cannot be fixed.
Smart swaps
- Black sesame seeds: These are sold at most Asian grocery stores and are significantly cheaper there than at mainstream supermarkets. If you only have white sesame seeds on hand, they work but produce a pale, milder result — the flavor is less bitter and the color will be cream rather than gray.
- Whole milk: Half-and-half is a fine substitute. Avoid low-fat or skim milk; the fat content is what gives the custard body.
- Heavy cream: No swap here — this is what keeps the ice cream scoopable rather than icy. Don’t reduce it.
- Granulated sugar: Caster sugar dissolves slightly faster but behaves the same way. Skip the garnish of sesame brittle or fancy toppings — not worth the extra dish when the ice cream itself is the whole point.
- Vanilla extract: A small amount of almond extract (use half the quantity) works if that’s what you have, though it shifts the flavor profile noticeably.
Keeping it fresh
The finished ice cream keeps well in the freezer for up to two weeks in an airtight container. Press a sheet of plastic wrap directly against the surface before sealing the lid — this prevents ice crystals from forming on top. The custard base (before churning) can be made up to two days ahead and stored in the fridge, which actually helps: a longer chill produces a smoother churn. If the ice cream freezes rock-solid after a few days, let it sit at room temperature for 8 to 10 minutes before scooping. Do not refreeze ice cream that has fully melted.
Common problems and fixes
- Ice cream is icy rather than creamy: The custard was not cold enough before churning, or the ice cream maker bowl was not fully frozen. Chill the custard overnight and make sure the bowl has been in the freezer for at least 24 hours before use.
- Custard curdled or has lumps: The heat was too high or the eggs were added too quickly. Strain the custard through a fine-mesh sieve before adding the sesame paste — this catches any cooked egg bits and saves the batch.
- Sesame flavor is weak in the finished ice cream: The seeds were not toasted long enough, or the paste was too coarse. The oils in the seeds carry the flavor; under-toasted seeds produce a flat result. Toast until you can clearly smell them.
- Ice cream won’t churn and stays liquid: The mixture was not cold enough going in, or there is too much sugar relative to fat. Make sure the custard is fully chilled — cold to the touch throughout, not just on top — before starting the machine.
- Color is dull gray rather than deep charcoal: This usually means the paste was not fully incorporated. Blend the sesame paste into the warm custard (not cold) and whisk thoroughly before chilling, so it emulsifies properly.
Black Sesame Ice Cream
Equipment
- Ice Cream Maker
- Heavy-bottom saucepan
- Whisk
- Blender or mortar and pestle
Ingredients
- 1 cup black sesame seeds preferably toasted
- 2 cups heavy cream fresh and chilled
- 1 cup whole milk
- 4 large egg yolks preferably organic
- ¾ cup granulated sugar
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
Instructions
- Toast black sesame seeds in a dry skillet over medium heat until aromatic, approximately 3 minutes. Allow them to cool.
- Grind cooled sesame seeds into a fine paste using a blender or mortar and pestle.
- In a heavy-bottom saucepan, bring the heavy cream and whole milk to a gentle simmer over medium heat.
- In a separate bowl, whisk together egg yolks and granulated sugar until pale and thick.
- Slowly temper the egg yolk mixture by gradually adding simmered cream and milk while whisking constantly.
- Return the mixture to the saucepan and cook over low heat, stirring constantly, until it thickens to coat the back of a spoon.
- Stir in the black sesame paste, vanilla extract, and salt until thoroughly combined. Chill the mixture completely in the refrigerator.
- Churn the chilled mixture in your ice cream maker according to manufacturer's instructions. Freeze until firm.
Notes
Tammy’s Tips:Â
- Consider adding a tablespoon of honey for a floral sweetness that complements the nutty sesame flavor.
- For a nut-free version, substitute with sunflower or pumpkin seeds.

Your questions, answered
Do I need an ice cream maker for this recipe?
Yes — this recipe is written specifically for an ice cream maker and the recipe card does not include a no-churn method. A no-churn version would require a different base (typically whipped cream folded with sweetened condensed milk), which changes both the texture and the ratio of sesame paste needed.
Can I use pre-made black sesame paste instead of grinding my own?
Yes, jarred black sesame paste works and cuts prep time significantly. Check the label first — some commercial pastes are already sweetened, so you may need to reduce the granulated sugar in the recipe to avoid an overly sweet result.
Why does my custard need to chill completely before churning — can I speed it up?
A fully cold custard churns faster and produces smaller ice crystals, which means a smoother final texture. You can speed up chilling by placing the custard bowl inside a larger bowl filled with ice water and stirring occasionally — this brings it down to temperature in about 30 minutes instead of several hours.
