There are nearly as many ways to get the bitter tannins out of the acorns as there are people who eat them, which is to say, um, at least a dozen. Different species of acorns also taste different, and will act differently in the kitchen. Some are oily, some more floury, some light, some dark.
The fruit of an oak tree inspired the shape of the Vita Copenhagen Acorn Pendant, a simple glass shade capped with black silicone that reflects a brilliant amount of light. The finish option determines the color of the aluminum on the inside of the pendant (the matte black top remains the same), altering the reflection given off once lit.
