In this show we chat to Alex Wright, co-founder of DASH water, who make natural sparkling drinks from wonky fruit and veg that would otherwise go to waste. We speak about DASH, food waste, drinks trends, and summery cocktails. Cook and host Kat shares another asparagus recipe and forager Imogen talks us through Alexanders – a common plant whose stems are tender and delicious, and seeds are wonderfully spicy.
