Sorry, only just managed to check in.
As long as it's not smoked, most plain Mackerel is free. Flavoured can be synned, but there are some tinned flavoured mackerel's that are free, John West is a great one
Thanks, it’s my first weight in tonight and I’m hoping to lose 6lb . No more smoke kiln dried mackerel for me as I didn’t understand syn value.now I’m loving tinned pilchards on my baked potato 😋
