definitely jelly on top BECAUSE that way the PB doesn't stick to the roof of my mouth. This is from an anti-PBJ/peanutbutter in general person though.

I NEED ONE.

@hungrychristel: lol, I thought those were noodles coming out of his eyes!

I think everyone should have one of these. Kind of reminds me why I used to collect key chains as a kid.

I have one...it's awesome!

Jelly on top! It just feels right.

And besides, the whole double PB layer thing makes the jelly squish out of the middle. It's got to adhere to the bread enough to stay inside.

It's always been pb on the bottom (or slice of bread on the left of the plate, to be exact) and jelly on top of that for me. Then the naked slice of bread (or the one on the right side of the plate) gets smooshed on top.

That goes double for when I toast the bread - that way the heat from the toast makes the pb all yummily melted. Mmmmmm.

I also put a layer of PB on both slices and then the jelly on one slice. I do have an unusual way of cutting the sandwich though:

I like to cut the sandwich slightly off center, so one half is bigger than the other. When I eat the sammy, I eat the small half first - and then when I get to the big half I feel like I'm getting a bonus! My husband used to tease me about this, but I know he thinks I'm a sandwich genius.

Peanut butter spread on one slice. Jelly spread on second slice of bread. Invert peanut butter slice on top of jelly slice. Invert whole sandwich and enjoy.

Everyone knows you put peanut butter on both sides of the bread and the jelly in the middle, thus preventing the soggy jelly soak-in.

I actually had a PBJ for breakfast w/ my coffee this morning... I put the PB on the bottom while making and eating it. Never really thought about why, and I always cut in half into retangles.

i'm not o.c.d. about much, but i'm very particular when it comes to spreading...a thin layer (gloppy is bad) must carefully & evenly be put over the entire slice of bread. this compulsion also bleeds into play when i butter toast or put on mustard...i'm weird.
as for construction...using a knife, i do my jelly on top and the pb on the bottom. triangles are nice, especially if the crusts are cut off. i don't eat pb & js too often though.

I sounds like most people spread the PB first. I do it that way now, but growing up, there was a peanut allergy in our house, so I was taught to use jelly first, then close the jar and put it away to avoid cross contamination.

I wonder if spreading order has any correlation with top/bottom preference?
