Origine chocolate Ghana - soy sauce - nori caramel ice cream

Cut the cold butter into small cubes. Mix flours with the sugar and salt in the food processor. Mix all the solid ingredients in the machine with the paddle and add the cubed butter and hazelnut paste. Work until a homogeneous, sandy texture is achieved. Add the eggs at room temperature and mix until a compact dough is formed. Form two squares of approximately 800 g of dough and cover completely with plastic film. Leave to rest in the refrigerator for at least 4 hours. Roll out the dough to 2.5 mm thick. Leave the sheets to rest on a baking tray covered with baking paper in the refrigerator for an hour. Cut out with a 9 cm diameter ring. Oven settings: 160°C low fan, 0% humidity. Slightly underbake the biscuits.

Create a caramel with the sugars and heat to 140°C. Leave the caramel to cool, blend with the nori in a food processor, create a dust and set aside until ready to use.

Heat the milk, cream and invert sugar to 40°C. Mix the solid ingredients and sprinkle into the liquid part. Bring to the boil and pour onto the dark chocolate, emulsify well with a blender. Leave the ice cream base to mature in the refrigerator for 24 hours.
