Put at least 3 inches of oil in a large deep saucepan
. Turn the heat to high and keep it there until you can drop in a pinch of flour and it sizzles. To make the batter: combine the flour, baking powder, salt, spices and butter in a bowl. Add about 1/2 cup cold water and whisk
to the consistency of thick cream. Dip the vegetables into the batter and then slide them into the oil. Fry
each piece until golden. Drain on paper towels and serve immediately.
