Cook into an oven the pumpkin in a 200 centigrade degrees temperature during approximately a hour, remove the nuts and remove the skin.
Put the pumpkin's pulp into a cloth bag and leave it hung up all the night long in order to drain itself in a natural manner.
The next day, mix the obtained pulp, the sugar and the beaten yolks, then cook them during some 15 ó 20 minutes without stopping to stir.
Incorporate to the previous mixture, the ground almonds, the grated lemon and the cinnamon.
