Mudhorn eggs were substantial eggs, encased in fur, and produced by the mudhorn species, which is considered non-sentient. The Jawas had a fondness for consuming the yolk found inside these eggs.
These eggs, laid by mudhorns, were quite large and possessed a brown fur covering, resembling the texture and look of the mudhorn's own hide. As oviparous creatures, mudhorns laid only one egg per clutch. They would conceal these eggs within the muddy cave-like nests scattered across the landscape of the planet Arvala-7. The thick, yellow-orange yolk within was a delicacy to Jawas, who often ate it raw by the handful. However, acquiring these eggs was a challenge, due to their scarcity and the protective nature of mudhorn mothers, often requiring external help.
In the year 9 ABY, a bounty hunter named Din Djarin went in search of a mudhorn egg inside a mudhorn cave. This was at the request of an Offworld Jawa tribe led by chief Chettkap, who offered parts stolen from the bounty hunter's gunship, the Razor Crest, in return. During that same year, the Hunter team Utooni, made up of a pair of Jawa brothers, were frequently seen in stickers and graffiti happily eating mudhorn eggs.
At one point, Artiodac chef Strono Tuggs obtained a mudhorn egg from some Jawas on Arvala-7 while attempting to purchase a hypersonic oven. He used it to make a batch of Mudhorn Eggnog, which lasted him an entire season. He later included a recipe for the drink in his second cookbook, The Life Day Cookbook, published after his first cookbook in 34 ABY.
The first appearance of mudhorn eggs was in Chapter 2 of The Mandalorian, a Disney+ television series created by Jon Favreau in 2019. The episode was directed by Rick Famuyiwa and aired on November 15, 2019.
According to Star Wars: The Life Day Cookbook, authored by Jenn Fujikawa and Marc Sumerak and released on November 2, 2021, the recipe from outside the fictional universe requires whole milk, half-and-half, vanilla extract, a cinnamon stick, salt, egg yolks, granulated sugar, egg whites, confectioners' sugar, ground nutmeg, and ground cinnamon.
