The perfect treat for Halloween and the pumpkin season.
Caramelize the sugar, deglaze with the lemon and orange juice. Add cinnamon, buttermilk and pumpkin mousse, puree everything finely and allow to cool.
Melt the white chocolate and heavy cream over a water bath or microwave. Add the chilled pumpkin puree. Pour the mixture through a fine sieve and into a 0.5 l iSi Whipper. Screw on 1 iSi Cream Charger and shake vigorously.
Cool the filled Whipper in the refrigerator for a min. of 6 hours.
For the brownie, melt 250 g of chocolate and 450 g of butter. Mix in 500 g of fine-grained sugar and 8 eggs until foamy. Add the chocolate/butter mixture and 200 g of flour.
Pour the prepared mixture onto a greased sheet and sprinkle with 200 g of whole hazelnuts. Bake for about 20 minutes at 180 °C until it is slightly detached from the edge.
Leave in the oven for 10 minutes if necessary. Immediately serve the brownie with the pumpkin sauce.
