Dust off those pans. Shake out that whisk. Break out that…er…rock hammer. It’s time once again for the Great Geobakeoff!
For the past 5 years, the Geological Society of London has hosted a friendly competition with a delicious twist. Scientists from around the world show off their baking prowess with geology-inspired challenges that delight the taste buds and showcase the staggering geologic diversity of Earth, space, and fantastic worlds.
This year’s competition took geobakers from the breathtaking vistas of Mr. Darcy’s Derbyshire to a galaxy far, far away to places a little closer to home. The contest isn’t over, so we’ll be on the lookout for more geologically inspired confections. But in the meantime, check out some of the many geoinspired treats this year that we just want to gobble right up.
On your mark…get set…bake!
