Remove the flour mixture from the heat and add the chopped nuts. Nuts need to be pre-fried in a frying pan or, like mine, in the oven. Almonds still need to be peeled. To do this, lower it into boiling water for a couple of minutes, and then throw it on a sieve and, pressing your fingers on the rounded end of the nut, release it from the skin.
Then, stirring constantly, pour in the syrup until a thick homogeneous mass is obtained.
