Hi, I’m looking for ideas from people who eat tinned oily fish such as mackerel and sardines on what to do with them. I’ve bought some mackerel in spicy tomato sauce but realised I’m not actually sure how to serve it! I’ve seen people talk about having these / sardines on toast, but do you eat them cold from the tin spread on the toast or are you supposed to heat them up? Tuna I’d usually eat cold mixed with mayonnaise and sometimes use it in pasta sauce. So I feel a bit daft not knowing how to eat other tinned fish but it was never eaten in my house growing up so I have no reference point!
