Lampreia de Ovos

In this egg-based Christmas dessert, Portugal celebrates a prehistoric bloodsucking fish.

Portuguese nuns have doubled as egg yolk–slinging pastry chefs for hundreds of years, but lampreia de ovos is one of their most unique offerings. This dessert replica of a terrifying, ancient sea monster—made from 50 egg yolks—is a Christmas tradition.

According to popular lore, nuns made eggs a convent staple after discovering that egg whites kept their habits sharp and wrinkle-free during ironing. After laying claim to Brazil in 1500, Portugal started importing sugarcane as an abundant, inexpensive ingredient. Resourceful nuns looked at all the extra egg yolks and, with the nation’s gold mine of sugar, began creating rich, yellow desserts to support themselves.

But why the lamprey, an eel-like, bloodsucking fish with several rows of spiraling, sharpened teeth, of all things? As one travel guide puts it, the Portuguese “so love this ugly river fish they make golden egg effigies of it for festive occasions.” For hundreds of years, the fish served as a suitable red-meat replacement (its texture is comparable to slow-cooked beefsteak) for penny-pinchers and Christians abstaining for Lent. The oldest known Portuguese cookbook, dating back to the 16th century, includes only one fish recipe. It’s for lamprey. A stew made from the fish and its blood is still popular throughout the country.

Lampreia de ovos requires no actual parts of the lamprey. All you need to make one is sugar syrup, almonds, and eggs. First, build your lamprey’s winding body from a paste of sweetened yolks and grated almonds, then dress it in sheets of yolks and syrup (“capes”) and strands of beaten egg and sugar. Once you’ve assembled the lamprey’s basic shape, you can brown it in a hot oven or use a red-hot iron to recreate its signature spots.

Finally, don’t forget to animate your new friend with a set of candied cherry eyes and a couple of peeled almond teeth. Top it off with sugary egg threads, then glaze and decorate with candy. Delicious, nutritious, and not so horrific after all.
