What is Adobo's secret ingredient?

My Filipina wife has been very remarkable with her special dish, the food her country is so proud of - ADOBO. She is definitely a great cook. Now, I’m thinking about surprising her in one of the foreign dating tours we’ll be attending soon. And my surprise would be preparing Adobo for her. I want to cook that dish to let her know that I respect her culture. She’s so special and I think she’ll be happy to see me cooking that dish just for her? So please tell me, what is Adobo’s secret ingredient? To make sure I’ll cook the best dish for her!
