A good BLT is top-tier, without a doubt but a BLT is really a tomato sandwich with bacon and lettuce, so it all rests on the quality of tomatoes and good tomatoes are hard to come by these days unless you grow your own.
Ham and tomato or cheese and tomato are also good. Make sure to use plenty of white pepper on the tomato though! Not black, and not freshly ground. The white pepper brings out the tomato flavour better.
I’m disappointed not to see the chip butty make an appearance.
Also disappointed, but not surprised, not to see the Sheffield fishcake butty in there. This, with lashings of salt and vinegar, is absolute god-tier levels of sarnie. I once drove a 280-mile round trip just to have a Sheffield fishcake butty for lunch. But most poor, unfortunate fools have never experienced the joy. The Sheffield fishcake makes other fishcakes ashamed and, in butty form, absolutely shits all over a fish finger sarnie.
Also, now I think about it, I used to enjoy the occasional roast pork butty with crackling and applesauce when I lived in Sheffield. Another glory that seems unavailable down south. Fuck, it’s grim down south.
