This simple, round-shaped Sardinian dessert employs a combination of ground almonds and sugar to create a thick dough that is then shaped into small-sized balls. Often elevated with the addition of lemon zest or orange blossom, gueffus balls are traditionally rolled in icing sugar and are always wrapped in colorful, decorative papers.

It is claimed that their name stems from the Spanish huevos, meaning eggs, because of their round shape. A staple at every festive event in Sardinia, these decorative treats are usually prepared in large amounts and are often given out as presents.
