Make the Tempura Batter and create the tenkasu. In another bowl, add the cored and finely sliced Napa cabbage, green onion, carrot, and pickled sushi ginger. After an hour, add the prepared vegetables to the pancake batter along with the ice-cold Brown Ale. Use your fingers to mix all the ingredients together well. This is also when other ingredients can be added to the batter. Try a quarter to a half pound of prepared calamari, shrimp, scallops, oysters, crabmeat, sliced smoked sausages, duck confit, shredded pork, etc.
