Mix the frozen blackberries with the sugar and the salt. Cover it with some wrap and then cook it on a double boiler for 4 hours. Once that’s done let it drain on a sieve that’s lined with a kitchen paper. Let it drain for a couple of hours, so you don’t waste a single drop. Then transfer the blackberry trimmings on a tray and let them dry at 60 degrees Celsius. I’m not using them this time, but it’s great to use for powders and ice cream.
white wine vinegar
Pour the blackberry broth into a saucepan and bring this to a boil. Meanwhile mix 25 grams of sugar with the pectin powder. Once the broth is boiling slowly while stirring add the pectin sugar and boil it for 2 minutes. Then slowly add 155 grams of sugar and the glucose syrup. Now heat it up till the pate de fruit is 108 degrees Celsius. Then stir in the white wine vinegar and boil it once more. After, heat up an oiled metal tray and pour the blackberry pate de fruit on top. Spread it and then use a blowtorch to remove any bubbles. Then let it set out of the fridge.
