I went Lidl today and got some tinned kippers but I can't find it on the app! I assume it's free because it's in brine but then I checked and it contains sugar? I put it through the syn calculator and it gives me mixed results! Either 4.5 syns for the whole pack or 6 syns so which one is it?! Lol. I'd be grateful if anyone could help me out? Thank you! Pics attached!
