I forgot to post this when I got back from my trip. I spotted an orange Coke bottle at Tesco's and had to buy and try. Tesco is sort of like Walmart and Target , a one stop shop type of place with tons of private label goods mixed in with better known brands. Tesco's supposedly coming to America with a mystery "format" that will apparently shake up the traditional food retail market. Interesting.
As you would've guessed, it tastes just like Coke with a little bit of orange soda mixed in. You can simply add a little Sunkist soda or any other orange-flavored soda to Coke and voilà! Or forgo the whole orange soda thing and just add a splash of orange infused Cruzan or Bracardi Rum instead =)
