L'maki nut

L'maki nut was a type of nut indigenous to the Delta Quadrant. When pureed, it made a lustery blue cream that was a popular cake frosting.

Neelix often enjoyed using pureed L'maki nut frosting on his baked goods and pastries while aboard USS Voyager. It was one of Kes' favorite foods. 

In 2376, while Tuvok temporarily suffered from brain damage, he enjoyed making several desserts, including cakes with L'maki frosting. 

Later that year for Tuvok's birthday, Captain Janeway replicated a cake with L'maki frosting for him.
