Tempura oysters with kelp & miso sauce

Kelp seasoning

1. Toast the nori sheet in a non-stick pan till it becomes very crispy. As it cools it should crumble very easily.
2. Remove from the pan, add the sesame seeds and lightly toast.
3. Place the nori and sesame seeds in a spice grinder and blend till very fine.
4. Remove and combine with the lime zest and salt in a small plastic sealed bag.
5. Shake the bag so the lime zest oil is extracted through the mixture.

Miso dipping sauce

1. Place all the ingredients except the spring onion into a small sauce pan and bring up to a slow simmer, constantly stirring with a wooden spoon.
2. As soon as it reaches a simmer, remove from the heat and allow to cool.
3. Add the spring onions and mix through.

Tempura batter

1. Beat an egg in a bowl.
2. Add ice water.
3. Add sifted flour to the bowl and mix lightly, not over mixing the batter.
