Uncle Ben's Express Rice in microwaveable pouches are not free, even the plain ones, because to make them work in the microwave they have a certain amount of oil on the rice, to keep it separate.
Long Grain Rice is 1 syn for a 250g pouch (these values are all for Green and EE)
Wholegrain Rice is 3 syns
Basmati Rice is 2 syns
Long Grain and Wild Rice is 1 syn
The flavoured ones range from2 to 6 syns.
The Tilda ones tend to be a little higher than the Uncle Bens.
The dried Sharwoods noodles are free on EE and Green, but the microwave and "ready to wok" ones are synned.
