Jammy eggs lie between hard and soft boiled, with a yolk that is not fully solid, but not a pourable liquid. The outside of the yolk is fairly solid, while the center is verging on runny—the gradients really show. They're great for snacking, of course, but they are even good for deviled eggs. The image at the top of this post is of eggs that are jammy, and they were delicious! Jammy eggs cook for a minute or two less than hard-boiled.
