Definitely mine would be Mole (Molé).
It's my favorite dish to make. It's always a special occasion when I make it. And it's always delicious. I started making it 20-some-odd-years-ago, and haven't changed it much in the last 15 years. I finally wrote it down in a PDF format that I will share here for the first time, about 5 years ago. Although Mole would be my signature dish, my friends and family often request Ribs, Grilled Salmon, Smoked Pork Butt, Wings and Burgers, As well as Breakfast. I make 'Chorizo con Huevos' almost every weekend, it's on deck for tomorrow morning, in fact.
