Heads up if you demolish Batchelor's rice packets like there's no tomorrow, because as of March 25th 2015 they now have a syn value due to the change in recipe.
Beef - 2 Syns
All the other flavours 1.5 Syns

Look out for the 100g packets which are the new recipe packets. A good idea though is to rush to your local B&M store, Home Bargains and similar as they will likely still have the old packets plus they'll probably be given the rest of the old packets that stores cannot get rid of?
