Each mouthful containing a sweet, crisp tempura battered oyster, with the sharpness of the wasabi mayonnaise and the refreshing cucumber salsa, plated beautiful, making it delicious to both the palate and eye. Let us show you how to recreate the dish.

How to Make Tempura Batter
The secret to a crisp tempura batter is to have it really cold, we use cold soda water and ice cubes. Keeping the batter cold allows less oil to absorb into the batter during the cooking process.
I use soda water as I like the aeration the carbonated liquid gives. You could also use sparkling water.
Make the batter thin, about the same consistency as crepe batter. Don't over mix once you have added the flour, as you don't want to develop the gluten.
My final tip for making great tempura batter, is to have the oil at the correct temperature. And keeping it at a consistent 180 deg C.
To Shuck An Oyster
To open or shuck an oyster might seem a challenge but it is really quite easy with a bit of practice.
You will need an oyster knife and a cloth. Hold the oyster firmly in a cloth, at the back end of the oyster where the shells join, firmly ease the knife between the two shells. Once the oyster knife slides in, give it a twist to pop the shells apart.
Slide the knife on the underside of the flat shell to slice through the muscle, this will remove the top shell.
Check for any shell that may have come off in the opening process. Try and keep all the natural oyster juice in the shell, this will keep the oyster moist.
Practice makes perfect, so keep trying and you will find the sweet spot of the oyster. Or you can always cheat and ask your fish monger to open them.
