Hello from tropical paradise!  My farm sitter is home with all my furry animal family and baking in the 100 degree temperatures while hubby and I escaped!  After a few days of soaking in the sun, taking in the aroma of all the tropical blossoms, listening to the waves gently washing ashore, we decided to venture out and try a new restaurant.  I simply love Thai food, so we chose Singha Thai due to all of the international accolades showered on the chef/owner and his culinary style.
Little did we know that one of the appetizers or ‘pupus’ as they call them here in Hawaii, is one of the top favorite dishes that Chef Chai created and serves at both of his award-winning restaurants.  To me, no ingredient represents Hawaiian cuisine more perfectly than Ahi Tuna.  So as curious as I am, after we returned to our room, I googled the recipe!  To my surprise this is one of the recipes that he shares with his fans.  It is simply incredible and even my husband who despises raw fish/sushi/sushimi was impressed.

This delightful appetizer consists of beautiful, fresh, red Ahi Tuna dipped in a tempura batter and then encased in a panko crust.  Then the tuna is fried for just a few seconds only so that the tuna stays raw inside.  Finally, it is plated and beautifully presented in a perfectly spiced curry sauce with a wasabi sauce drizzled around for that extra little Asian bite!  A tropical mango salsa marriage tops it all off!

This is literally a tropical culinary paradise in your mouth!
