Sainsbury's inspired to cook.....

My god these are nice....but have a hefty price tag to go with it! One thing i dont understand is how its free???

Tonight i had pork fillet medallions with a sweet bramley apple and red wine sauce. My food directory and the website says its free but the ingredients include: apple juice from concentrate, sugar, cornflour, butter and malt extract powder. How does it make it free?!?!

Out of interest what is it listed under because I can't find it online? It may be that the quantities of the synnable ingredients are so small when divided by the servings that the syns become neglible.
