If this question is asking whether heated, liquefied sugar (caramel) can be turned back into sugar granules, then technically, the answer is yes. It is very difficult and requires superheating and incredibly slow, gradual cooling to ensure the sugar reforms as crystals. The grade and quality of the sugar will almost certainly be significantly reduced.
