This is Adeline Waugh. She's a food stylist and author from Miami, FL, and the inventor of MERMAID TOAST!
Maybe you've heard of multicolored mermaid hair? Well Waugh created MERMAID TOAST! WOW WOW WOW.
Waugh told Food and Wine she made the swirly blue toast by adding blue green algae powder to some of her own homemade almond milk cream cheese. (We're pretty sure regular cream cheese would work, too).
She also styled "unicorn toast" which is basically toast slathered with different naturally-colored cream cheeses.
Here's some unicorn toast with sprinkles on it (and a bit of gold leaf on top).
