I didn't hang around to find out, as they were so hard that we Americans were actually banging them on the sides of the tables lol! The local market near my university had a section of expensive imported 'American Foods' Including tiny "American-style pancakes" and you could get a pint of Ben & Jerrys for the equivalent of about $12 in Euros.
Mayo was tan-colored (not white at all) and came in these big long tubes (like toothpaste, but bigger). We actually asked the store if the mayo had gone bad or something, but they told us that our white US mayonaise was artificially colored to make it look that way.
Oh, and they sell sex toys right in the retail store at the mall I went to. I was shocked to see giant dildoes and dongs right on the end caps next to kitchenware. Gotta love those Germans! :)
Mayo is water, oil & egg.
If you use a yellow oil, and/or yellow-orange egg yolk, it will come out a muddy light yellow color.
So, use a very pale oil, mostly egg white, and some bleach, and you get american mayo.
And those tubes are creepy. Like grabbing a large worm.
Also, chedder cheese is snot colored. We in America dye it orange.
