Put a saltspoonful of salt and a half drop of Tabasco (if admissible) into a bowl or soup plate, put in a piece of ice the size of an egg, rub the salt with the ice until the salt is dissolved, pour over two tablespoonfuls of olive oil, stir a moment, remove the ice, add a teaspoonful of lemon juice or vinegar and beat a moment until the dressing is rather thick and opaque. Use at once. This will be sufficient for one person.

The flavoring of the dressing may be changed by rubbing the spoon with a clove of garlic, adding tarragon instead of plain vinegar, or sprinkle various chopped herbs over the lettuce.
