Method of preparation:

1) Sugar, glucose syrup, citric acid, water and the GRINDSTED SMS are mixed.
2) The mix is heated to e.g. °128C, while agitating.
3) The sugar mass is whipped in a Hobart mixer that is connected to a °100C hot oil bath, and the filling is whipped till the desired overrun is obtained.
At this stage, the below-mentioned test is performed*
4) DIMODAN HR1 or DIMODAN HP1 is added to °40C warm tahini, and it is mixed well.
5) The sugar mass and the tahini are mixed manually. First it is folded gently, then the layers of tahini and sugar mass are folded by hand over and over again with a pulling movement.

Test

*) A small amount of whipped sugar mass is removed with a rubber spatula. A small square of 3-2 cm size and about 3-2 mm thick is formed with the fingers. The square is submerged into cold water for 10 to 20 seconds, removed from the water, and surplus water is allowed to drip off. If the sugar mass breaks into pieces after applying a weak bending force between two fingers, the sugar mass is acceptable and suitable for further processing.
