Panellets are a very special treat from Catalonia.
Cook and peel the potatoes. Push them through a ricer and let the mass cool down.
Mix the almonds, sugar and potatoes and knead to a mass.
Rub the lemon zest and add. Stir everything well.
Form the mass into 2-3 cm thick balls and roll them in the egg.
Bake the Panellets in the oven at about 170 C, until they are golden in colour.
The Panelletes can also be rolled in crunched peanuts, powdered with sugar or decorated with candied fruits.
