mix it with mayo for sandwich spread.Wasabi is great in small quantities on grilled fried or raw fish.Good on nuts too if you have the Wasabi powder make it real thick and use soy sauce instead of water then mix into a bowl of nuts for a hot snack.
My friend makes wasabi devilled eggs - they are fabulous! And, mixed with sour cream as a baked potato topping. Toss warm pasta with whipped cream cheese, salt, pepper, and wasabi paste - instant spiced up alfredo!
Mix some into a little bit of whipping cream to blend, then add more whipping cream and beat until stiff. It makes a good topping to seared ahi (or grilled halibut or swordfish) - light and with a kick!
