> Joël's Discovers the Foam, Dec 2014

> While actively looking for egg substitutes, Joël Roessel, a ténor from France, discovered through a systematic investigation into vegetable foams, that liquid from red kidney beans and hearts of palm can be coerced into a foam in the same way as flax mucilage. He posted his results on his blog at revolutionvegetale.com, providing a key contribution to unlocking the secret of aquafaba.
