The best way to layer a BLT is to toast the bread, then spread mayonnaise on one side of each slice of bread.
Then on the bottom slice of bread, place some lettuce first, then add seasoned tomato slices and then the crispy bacon.
After that you add the second slice of bread, which completes the BLT sandwich.
What makes a perfect BLT is to toast the bread, add some mayo and then add the bacon, lettuce and tomatoes.
Hellmann's mayo is best on a BLT sandwich although other mayo is also good.
You should not put cheese on your BLT if you want to make a traditional BLT.
A traditional BLT does not contain any cheese and only contains bacon, lettuce and tomato, which is what the BLT stands for.
But you certainly can add some cheese to your BLT which would make it a bacon, lettuce, cheese and tomato sandwich or a BLCT sandwich.
You can also add some avocado or fried egg to create variations of the BLT.
The country that invented the BLT is the United States although the BLT also has roots that can be traced to English Tea sandwiches and the rise of the club sandwich that included bacon, lettuce and tomato.
The BLT sandwich that we know today originated in the early 1900s in the United States and is a variation of the club sandwich and gained popularity after World War II as a result of increased access to fresh ingredients at year round supermarkets and also due to the BLTs convenience for working women.
The exact inventor of the BLT is not known but we do know that the BLT did originate in the United States in the early 1900s.
The BLT also is thought to have roots in English tea sandwiches that were served during the Victorian era, although the exact combination of bacon, lettuce and tomato was not developed fully then.
And the modern BLT sandwich that we know today is actually a descendant of the club sandwich, which also first appeared in American gentlemen's clubs in the late 19th century or early 20th century.
And a 1903 Good Housekeeping Everyday Cook Book also contained a recipe for a club sandwich, that also included bacon, lettuce, tomato and mayonnaise and also a slice of turkey, which set the stage for the BLT that we know today.
The popularity of BLT's also surged after World War II as supermarkets became much more common and made the ingredients in BLT's available year round.
The BLT was also a convenient and quick to eat lunch in the workforce in large numbers during and after the war.
And by the year 1958, Hellmann's Mayonnaise was also advertising the BLT as a traditional sandwich, which further cemented the presence of BLT's in the American diet and culture.
