Singapore-based WhatIF Foods uses an obscure African legume called the Bambara groundnut to make both milk and noodles. Drought-resistant Bambara groundnuts not only grow in marginal conditions, they release nitrogen to improve soil fertility. "The plant doesn't need a lot of care and attention," explains WhatIF Chief Commercial Officer Andrew Reeves. "It doesn't need any fertilizers or any pesticides and it will find its own water. This plant developed really long roots so it will go wherever the ground water is; it will find it."
