Grandmam's Roast Rabbit - +3432 Health and Stamina and additional +3120 Stamina.
If this recipe works as advertised it provides far more benefit than a purple VR10. Unfortunately, I cannot test it since I don't have the materials for it.
I am inclined to believe this is a bug since Health and Stamina have the same value in the first part of the recipe while all the other recipes are scaled properly between Health and Stamina/Magicka by 1.1x.
