Goose eggs are big. Really big – at least compared to other types of eggs. You can use them in any recipe calling for eggs. A good rule of thumb is simply to use one medium goose egg for every two large chicken eggs. Like other eggs, though, goose eggs vary in size, so you'll need to use some judgment as to their volume based on the specimens you have in hand.
Goose eggs are very richly flavored. As goose meat is to chicken, goose eggs are to chicken eggs. Richer, fattier, heavier, and more deeply colored. Some chefs particularly prize goose eggs for making pasta, claiming a superior flavor and texture in the final product.
Goose egg shells are also much harder than chicken egg shells, making them popular to use in crafts. Because of this, however, they can also be a bit of a challenge to crack, requiring greater force to crack them open and a greater chance of breaking the yolk in the process.
