I have tried to make Tiramisu chocolate mousse from this video many times. The chocolate mixture turns out great. With the egg yolks I add grape juice instead of wine and soft cheese instead of marcarponi - which seems to turn out great as well.
What I fail to make is the whipped creme. I use Dano sterilized creme that is modified with vegetable oil (so it says on the can), fat 23%, made from skimmed cows milk and it says the milk fat is replaced by veg fat. I put the bowl and the whisk in the refrigerator, as well as the creme, but when I whisk it, it becomes more watery than fluffy.
So today I got Fostered Clark's Powder Whip Wonder Whip Topping; that turned out nice and frothy, but when I combined it with the chocolate-egg mixture, it did not turn out to be the way it looks in the video. I had to put it into the refrigerator so the mixture became a little more firm; I could barely hold a shape in the martini glasses.
What am I doing wrong?
