This is a very delicious Walnut Crumble. It is not just my personal opinion, but lots of my International friends, Portuguese, Chinese, Hungarian, you name it, all love it. I think the secret is the usage of butter. For this recipe, we use only 2 cups of flour and 3 tablespoons of sugar. With 3 egg yolks, we mixed it to form a dough. Halved it, one part at the base of the Walnut Crumble, the other half we leave in the fridge for about 30 minutes to rest. The 3 egg whites will be beaten until fluffy with soft peaks, and we add the finely ground walnuts (150g) and gently fold it. At this stage, we add about some powdered sugar as well as 8 tablespoons of apricot jam. This will all form the second layer. Finally, using a cheese grater, grate the chilled dough to create these crumbly topping which forms the final layer. Viola! Hope you enjoy this wonderful dessert.
