idk, I'd question how much of that is just in people's heads (like the blind taste tests of sugar v HFCS where people couldn't tell the difference)
most can definitely tell the difference.
i've done plenty of blind taste tests with throwback pepsi and hfcs pepsi and almost everyone could taste the difference.
in foods, however, it's different because they use hfcs42, where the sweetness level is way lower than regular sugar. they need to use much more of it in order to match the equivalent sweetness that sugar would achieve.
anyways, i'm going into a different topic altogether that, for some reason, is a hot button topic in the forums... so, i'll leave it alone.
yeah, tastebuds change... that's true. however, for some reason, fun size just tastes different than full size. full size tastes better and has a better texture altogether than fun size.
reese's peanut butter cups are totally different tasting based on size and shape. for example, the easter egg shaped cups taste different than the normal cups... the reason is the peanut butter to chocolate ratio. depending on the shape and size up the cup, you end up with different proportions of ingredients. it is my opinion that the mini reese's peanut butter cups are the best tasting of all the shapes and sizes of cups reese's has to offer... second best is the egg-shaped reese's peanut butter cup.
