This is wonderful! I made this on 22 Nov 2016 and was an instant two thumbs up from my Thai wife. Excellent marinade as written, recipe followed as written, no changes needed, and after baking, spoon the oil on some pasta for a great meal.
I bought 4 fillets, Norwegian import, 69 Baht for 140 to 160 gram fillets. I figured the servings as 1 fillet per serving. For 69 Baht per fillet, this is about $2.03 per serving. High cost but great for a once in a while meal.
