Rinse the anchovies under cold water and pat dry with a paper towel. Cut the anchovies to the sizes of the sage leaves (you might not need them all depending on the size of the sage leaves). Sandwich one anchovy between two sage leaves.
Put 1.5 inches of oil in a pan and turn on to a medium heat. Mix the flour and water in a mixing bowl and whisk until combined.
One at a time dip the sage leave sandwiches into the batter so it is completely coated then place carefully in the hot oil. Fry until slightly golden on each side.
Serve immediately with wedges of lemon and a sprinkling of salt.
