Beer batter makes a crisp and light coating for fish fillets, leaving them moist and succulent. Rapeseed oil is fabulous for deep-frying, it is one of the few oils that can be heated to a high temperature without losing its nutty flavour, colour and antioxidants. Rapeseed oil has many health benefits, it is high in mono-unsaturated fats, low in saturated (less than olive oil) and rich in omega 3.
It is important to use a shallow, heavy based frying pan, pour in just enough oil to fry the fish in without overflowing.
The oil can be re-used several times, simply filter when cooled.
