I once saw Gary Rhodes cook something similar on an oilrig and I’ve been working on it ever since (not the rig that is). Combining many flavours this makes a perfect supper and again is simple and quick to cook. The holy trinity of Mustard, beer and cheese – the mainstay of the rarebit, always hit the mark. Any white smoked fish will do, dyed or un dyed. Add the tomatoes and this is so much more than cheese on toast.
