That looks mouth watering! I haven't thought there's more recipe to make from a sardines. Here in the Philippines although not true for every Filipinos, we love to eat the sardines as it is. Just add some spicy vinegar or soy sauce and it's all good to eat. Some would like it sauteed with garlic and onions and it's already good. Yours looks like a sophisticated dish made from sardines! You're really good at cooking. Very artistic!
