Tempura Oysters with Lime and Wasabi Mayonnaise

Summertime special: tempura oysters with lime and wasabi mayonnaise.

This was the first time I have ever had oysters at home. For some reason I always thought that oysters are more like a restaurant treat – that shucking is a mess and they are too perishable for home delivery. Well… allow me to report: delivery is fast & reliable, the packaging keeps the products chilled – and fresh oysters can actually be stored in the fridge for a few days. Moreover, shucking was not at all as messy as I imagined but actually rather easy: a towel and an oyster knife was all that I needed. I ate half of dozen as I was shucking it, topped with a classic mignonette. But for the other half I wanted to do something special.

My first encounter with a-la-carte tempura was at a Japanese restaurant a few years ago. It was a demo performed by the famous tempura shokunin Shuji Niitome. He invited all the guests in the kitchen, where he cooked and served the tempura on the spot: no fancy plates, no service: just plain, pure pleasure of cooking – and eating.

My tempura oysters recipe is probably far from that Japanese absolute perfection – but as a home cooked version I’ll say it’s pretty good.
