Vietnamese Open-Face Cobia Tacos


Vietnamese Open-Face Cobia Tacos

Sometimes I get really really excited about developing recipes for a contest. I just can’t get enough of the sponsor’s product. So it is with Open Blue Cobia. I can’t stop thinking about what TasTy dishes I can make with Cobia. I tried deep frying Cobia and of course, the texture was perfect. I liked it but I thought the puffy batter hide the distinct flavor. Then I thought of a taco with Cobia two different ways! I could poach some of the Cobia in lemongrass ginger broth then use sashimi Cobia with a light sauce on top. I crafted a well balanced Vietnamese Sauce. The sauce has heat, sweet, and just enough lime juice to make it fresh. Ohhhh how I love my sauce….how my Cobia loves it too! What fun to have Sashimi Cobia and poached Cobia all on one taco! This dish shows how versatile cooking with Cobia can be! #CobiaCookoff

I must brag a minute, my latest Cobia creation, Vietnamese Open-Face Cobia Tacos, taste like the most memorable taco you have ever eaten while walking along the sandy beach on some exotic shoreline. It is innovative…who has ever heard of an open-face taco with a Vietnamese twist? Intriguing ~ indeed!

I am craving it right now even though I just finished off the rest of the Cobia mixture from 10 hours ago. The texture was still perfect! I think the sashimi Cobia had cooked in the Vietnamese sauce…think the most incredible ceviche. Yum!

Time for me to retire to bed and dream of exotic sandy beaches and lil’ huts that sell the most memorable Vietnamese Open-Face Tacos!
