I choose this option every now and again. Recently there seems to have been a dearth in relatively cheap tinned sardines in oil that I was used to buying, I assumed they were imported. This mornings offering was Cornish sardines in salt water, less sardine in the can, but a significant difference in flavour and smell. Somewhat dearer in price, but I will choose these from here on in.
Served on a slice of malted bloomer and Welsh butter, with black pepper and fresh lemon. 10/10.
