First make the dressing. Place the garlic, anchovy
fillets, lemon juice, mustard and egg yolk in a
small bowl and season with pepper.
With a hand-held
blender or a small whisk, mix well until combined.
Slowly drizzle in the olive oil, mixing all the time
to form a thick creamy dressing; if it is too thick,
add a little water.
Heat the vegetable oil
in a frying pan until a small piece of bread sizzles
immediately when dropped in, then fry the cubes of
bread, turning them when they are golden.
When they
are golden on all sides, drain on kitchen paper. Put
the lettuce into a bowl, pour over the dressing and
2 tablespoons of the Parmesan, and mix well.
Serve the salad in a large bowl or on individual
plates, sprinkled with croutons and the remaining
Parmesan.
