Ok, I'm sure someone has gone over this before, but what is the easiest way to crack a guinea egg? I had a strong craving for homemade ice cream this morning and the first of the guinea eggs were all I had, so I used them, but I had a heck of a time getting them cracked to put in the blender. BTW, still waiting to see the final result in the ice cream. Looks really good so far! Thanks for the answers in advance!
