Use an ale yeast, which will leave a little more sugars when fermented all the way. But really the way to get apple flavor back into dry cider is to age it. No, not one month, not two months, not even 4 months. Just stick it away and let it sit.
Also, you don't expect dry white wine to taste like grapes do you? dry mead to taste like honey? so why do people expect dry cider to taste like apples?
