Ive just realised after enduring the "return of mcoz" ads (how timely)during the tennis that maccas herald the "classic kechup"sauce as a feature ingredient. HELLOOOO maccas in Australia it is generally referred as TOMATO SAUCE ,DEAD HORSE NOT KETCHUP .( Just as well they didn't feature some bogan wally draped in a flag with a hand over his heart chompin down a "MC OZ" WITH FRIES and COKE
BTW Raffa jst made a cuple of classic shots against FED
Food science asside...
When yo eat a maccas burger
Your brain smacks to the mustard, ketchup and sugar bun, and mayo if you eat a mac
Just buy american mild mustard, heinz ketchup and leave your mayo in the sun for a couple o hours, then with some sugary hamburger buns you got a better maccas burger when you add ACTUAL meat
