Tahini and chocolate look like close relatives. Technically they are two different fat systems, and joining them takes care.
How do cocoa butter and sesame oil differ?
Cocoa butter is solid at room temperature, with a melting point around thirty-four degrees.
That sharp melting point gives chocolate its sensation of melting in the mouth.
Sesame oil is liquid at room temperature, melting at minus six.
Mixed together, the melting point of the blend falls.
The result is a chocolate that softens at room temperature.
| Fat | Melting point | At room temperature | Crystal structure |
|---|---|---|---|
| Cocoa butter | 34 °C | Solid | Polymorphic |
| Sesame oil | -6 °C | Liquid | None |
| Milk fat | 32-35 °C | Semi-solid | Complex |
| Palm oil | 33-39 °C | Solid | Simple |
| Coconut oil | 24 °C | Semi-solid | Simple |
Why does tempering get harder?
Tempering is the process that sets cocoa butter in the right crystal form.
The right form gives chocolate its shine and its snap.
Sesame oil disrupts that crystal network, settling between the crystals and interrupting the order.
As the tahini rises, tempering gets harder and the product loses its shine.
That is why the proportion stays limited.
What proportion of tahini applies?
Eight to fifteen percent of the total weight.
Within that range the chocolate still tempers and holds its form at room temperature.
Above twenty percent it softens and will not hold a bar shape.
Below eight percent the aroma of the tahini goes unnoticed.
Used as a filling the proportion can run higher; the filling sits inside the bar and gets supported from outside.
How does the tahini go in?
The chocolate melts and comes to thirty-two degrees.
The tahini comes to the same temperature before going in; cold tahini thickens the chocolate.
Stirring stays gentle; air bubbles are unwanted.
The mixture goes into moulds and gets vibrated.
Cooling happens slowly at fifteen degrees; rapid cooling leaves a bloom on the surface.
Which chocolate goes with tahini?
Dark chocolate gets chosen, at sixty to seventy percent cocoa.
The natural bitterness of tahini agrees with dark chocolate.
With milk chocolate the product runs too sweet and the tahini disappears.
White chocolate makes an interesting pairing; the bitterness of tahini balances its sweetness.
Chocolates high in cocoa butter get chosen; their tolerance in tempering is better.
Which tahini goes into chocolate?
Plain tahini, made from sesame and nothing else.
Tahini with added sugar upsets the sugar balance of the chocolate.
A medium roast gets chosen; dark-roasted tahini brings the bitterness forward.
Tahini from hulled sesame is softer and agrees better with chocolate.
The jar gets stirred thoroughly before use.
What is the texture of tahini chocolate?
Softer and creamier than classic chocolate.
It does not give a sharp snap when broken.
It melts faster in the mouth.
Particles of tahini leave a slight graininess, which counts as the character of the product.
The texture relates directly to the proportion of tahini.
Where does it stand on gluten?
Both tahini and chocolate are naturally free of gluten.
The problem lies on the production line; where wafer or biscuit chocolate runs on the same line, contamination follows.
Certified products control that risk.
Where the label says may contain gluten, the product does not suit anyone with coeliac disease.
Products tested below the twenty-parts-per-million threshold get chosen.
What is the nutritional value of tahini chocolate?
A hundred grams carries 550 to 600 kilocalories.
Fat runs 38 to 45 grams, from cocoa butter and sesame oil together.
Carbohydrate sits at 35 to 42 grams.
Protein comes to 8 to 11 grams, pulled above classic chocolate by the tahini.
One square weighs about ten grams, so 55 to 60 kilocalories.
Where does tahini chocolate get used?
Eaten straight as a bar.
Offered beside coffee.
In pastry work for ganache; a tahini ganache gives a softer consistency.
Melted into biscuit and brownie recipes.
Produced as a spread too, where the tahini proportion can run higher.
How does the sesame allergy get declared on chocolate?
Sesame sits on the mandatory allergen list.
In tahini chocolate that allergen is unavoidable and appears in bold on the packaging.
Where soya lecithin goes in, soya joins as a second.
Where milk chocolate gets used, milk is the third.
Where the line also handles hazelnut, that information appears too.
How does tahini chocolate get stored?
Somewhere cool and dark, at fifteen to eighteen degrees.
It does not go into a fridge; condensation causes sugar bloom on the surface.
Above twenty-five degrees it softens, and earlier than classic chocolate because of the tahini.
Shelf life runs six to nine months, shorter than classic dark chocolate.
Rancidity of the sesame oil sets the limit, so the packaging stays opaque and airtight.
When does it get chosen over classic chocolate?
For a customer looking for a local flavour.
In products where protein matters; tahini raises it.
In pastry work where a different ganache texture is wanted.
In spreads, where tahini supplies a natural fluidity.
Not where a long shelf life and the texture of classic chocolate are required.
How does tahini chocolate get tempered?
The chocolate melts at fifty degrees.
It cools to twenty-seven, and crystal seeds form at that stage.
It then warms to thirty-one, and the tahini goes in at that point.
As the tahini rises the working window narrows; a three-degree window in classic chocolate drops to one and a half in a tahini product.
That narrow window makes tempering nearly impossible in a home kitchen.
Industrial production controls the temperature automatically and the window causes no trouble.
Correctly tempered, the product gives a clear snap when broken; the absence of that sound shows the process fell short.
A bar that looks dull rather than glossy is telling the same story before it is even broken.
