On BLTs

I've spent a considerable amount of time researching this, and I've concluded there is an optimal way to make a BLT sandwich.  Specifically - it'll taste quite a bit better based on how you assemble the ingredients.

Now, first off, my BLT includes bacon, lettuce, tomatoes, mayo, American cheese, a fried egg w/ some onions blended into it, and toast.  Here's one assembled:

But here's the key point:  It matters how you order the components on the sandwich  Simply putting the ingredients together randomly will make your sandwich less than what it could be.  It just won't taste as good.

So when you arrange a BLT sandwich, I suggest this ordering - from bottom to top between the two pieces of toast.   The bottom being the bottom of the sandwich as you are eating it - so that it's closer to your tongue.
1.  MAYO:  putting the mayo here is much better than putting mayo on the top of the sandwich.  I sometimes would mistakenly put mayo on the top piece of toast and wonder why my sandwich was no good.  Put the mayo on the bottom.
2.  TOMATOES:  put the tomatoes on the mayo near the bottom of the sandwich.  I like slicing little Roma or cherry tomatoes best because they keep longer and might have more flavor, but any tomato will do.  Keep it at the bottom.  The sandwich will taste drier if you don't put the tomato at the bottom.
3.  BACON:  Yes.  Put the bacon on top of the mayo and tomato.  As you eat the mayo, tomato, and bacon will all merge together and taste best in this order.  You can try it, but I think if you put the lettuce or other ingredients "between" any of these 3 ingredients, it won't taste as good.  Usually the bacon is coming out of the skillet at this point in time during sandwich assembly, so it's straight from the frying pan onto the sandwich.
4. CHEESE:  I put a half slice of American cheese on top of the bacon, broken in two pieces.  I think it helps hold the sandwich together as the cheese melts, and it just tastes good there.
5.  FRIED EGG w/ ONIONS.  I used to not put an egg on the sandwich, but found out I like it this way.  As I pull the bacon out of the skillet I put an egg in, and toss in some chopped onions with it while it is cooking.  I crack the yolk and mix the onion pieces with the egg and it all cooks into a single fried egg "patty".  The onions make a difference.  When the egg is done I put it on top of the cheese, which I think it melts to to help hold everything together.
6.  LETTUCE: The lettuce is best put on the top of the sandwich.  I think partially - I like the texture of the lettuce, and it'll still give a good crunch on the top of the sandwich without interfering with all the good stuff at the bottom.  Also - if you put the lettuce in the middle of the sandwich things will slide around like crazy.  Lettuce has a high viscosity I guess.  Don't believe me?  Try putting the lettuce in the middle of the sandwich - you'll have a wreck on your hands, and the lettuce anywhere but at the top will make your sandwich taste less good.

And the final point to reiterate.  Make sure you eat with layer 1 on the bottom closest to your tongue when eating, and layer 6 toward the roof of your mouth.  

That's pretty much it.
