Used ginger ale and it made the livers taste kind of sweet. I prefer them soaked in milk instead of soda.
I LOVE chicken livers so this was a great new way to make them. I couldn't say that the 7-up did anything for them though...they just tasted like regular chicken livers to me...it may have helped brown them a little. I doubled the recipe and spread the halves out on a greased cookie sheet. Then I broiled them 6 minutes per side. I never thought of grilling or broiling liver...now I will be trying it again with different spice mixtures.
