You can work it out from the bag, just do 1 syn per 20 calories for the weight of the bag/100g or whatever and divide it by however many are in the bag/the 100g or whatever I expect it'll be about a syn or so each but I cant know for sure
Thanks ermintrude but it was a 290g bag that someone ad bought at work so I didn't av any scales or owt to weigh m on so just decided to play it safe n av 3 n count m as 3 syns to b on the safe side. Guna get a small bag at wknd now though cos I think 10 n half syns r worth it as I love m!
