Mole rat wonder meat is a craftable consumable item in Fallout 3, which can be made with two simple ingredients and access to the Wonder Meat Maker, located within the Jury Street Tunnels.
Mole rat wonder meat was first created in 2277 by a raider scientist named Ryan Brigg. According to his notes, mole rat meat becomes much more palatable after being cured in a metal box with wonderglue, producing a jerky which possesses a 'nutty aftertaste' and none of the natural bitter flavor.
The wonder meat itself is 4 times more effective at health regeneration than normal mole rat meat, while not altering the rad value whatsoever. Making it on par with mirelurk meat, but without incurring the usual danger, difficulty, and general rarity of finding and killing the creatures.
The wonder meat can be made very simply by taking a piece of mole rat meat and a tube of wonderglue to Ryan's Wonder Meat Maker and activating it, combining the two to create one piece of the wonder meat. They are not hard to find as these items are strewn all over the laboratory.
