The BLT: Why This “Simple” Sandwich Isn’t Simple at All
April is BLT Sandwich Month!
Now, I know what you’re thinking – a month to celebrate a BLT? How much time do you really need to celebrate a bacon, lettuce and tomato sandwich?
And I don’t disagree.
I could absolutely get behind a month dedicated to exploring the glories of bacon sandwiches – there are, after all, many kinds. But a BLT is just one of them. Do we really need four weeks to delve into the details of a BLT?
Well… having thought about it, we might.
Not because of some ancient pedigree. It’s not all that old – and probably more an evolution than an invention. It likely grew out of the tea sandwiches of the Victorian era – via the club sandwich – but really gained ground post–World War II, when fresh tomatoes and lettuce became available year-round.
The components needed for a typical BLT are: bacon, lettuce, tomato, mayonnaise and bread. But don’t let the simplicity of that list fool you.

This sandwich is a masterclass in culinary balance: the salt and crunch of the bacon, the acidity of the tomato, the cool crispness of the lettuce, and the creamy bridge of mayonnaise. Get that balance right and it’s perfect. Get it wrong and it’s… disappointing.
What makes a BLT a BLT
BLT lovers have strong views about every ingredient and every layer.
- What bread is the right bread? Should it be toasted or not?
- What is the right order of assembly?
- Should the mayo go on both sides or only one?
- Iceberg or romaine? Shredded or not?
Living in the UK as I do, I am also aware of heated discussions about which bacon puts the B in BLT – streaky bacon or back bacon? In the US, the bacon’s role is widely seen as bringing the crisp, so it’s streaky bacon all the way. We can get into the differences on Bacon Day – come back in September for that.
These are the sorts of things BLT obsessives debate. Hotly.
Poking the BLT Bear
Now, I am not one of those people who will stage a protest over the choice of lettuce, but I do enjoy the sheer spectacle of a foodie throwdown.
If you want to watch the sparks fly during BLT Month, try suggesting that if the tomato isn’t room temperature and lightly salted, the sandwich is a failure. Or wade in with an even bigger conversational grenade by asking, innocently, “Does it have to be white Pullman loaf? Can it be sourdough? What about… a bagel?”
What about “innovations”?
- Do we consider the BLAT (a BLT with added avocado) a true BLT?
- What about the BELT (a BLT that contains an egg)?
- What about even more out-of-left-field suggestions like wrapping the whole thing in a tortilla or replacing the mayo with mashed peas? I think we all know TikTok has a lot to answer for when it comes to these “viral food hacks” that have very little to do with food and everything to do with clicks.
No, true BLT lovers will stick to the authentic, original blueprint – debated as it might be. We don’t need an algorithm to tell us that bacon, lettuce, and tomato work; we just need decent ingredients and a sharp knife.
Hmmmm. Maybe we do need a whole month after all.
