First let me say, that I always find it less than amusing when someone changes an ingredient (or several) in a recipe and then remarks the dish was not as good as expected.
That said, I did change some of the ingredients in this recipe ONLY because I had chicken breasts on their last legs (so to speak) defrosted in the fridge and I had to cook them last night.
So I went ahead and made the marinade but substituted lime and lemon juice with margarita mix. What can I say? It's the only citrus I had available! But my, oh my, what a fantastic result! My husband raved about this chicken all night long and again today.
I was only able to marinate it for a few hours, and I used the broiler instead of the grill, but the results were still spectacular. Wonderful flavor and very tender! I think the key is to cook them only the amount of time required and not a minute longer.
I also reserved some of the marinade before soaking the breasts, so when they came out of the broiler I placed them immediately into the sauce. Oh my word. Heavenly. I mean, this is likely going to be the only marinade I use for chicken breasts for some time to come. Can't wait to try it with the actual lime and lemon juice! Now, I'm wondering how this would work with shrimp...or pork...
