Thames Water Recipe
2 bottles (small "Britvic" size) Orange juice
Fill with Coca-Cola
Pour the Orange Juice in first. Top up with Cola, the fizzier, the better. Stir.
It is best mixed without ice, but use cold ingredients. Also known as a "Muddy Puddle", this drink is dark brown in colour and looks revolting. It is guaranteed to turn heads if not stomachs. Nevertheless, the two ingredients compliment each other as the cola ends up not too gassy and the orange loses it sharpness.
