Jerusalem artichoke and sweet potato is a good root veg one too (possibly with tarragon IIRC, and half the veg roasted)
Is it good for the environment if you scale it up?
In comparison to conventionally-produced European meat, the team estimate cultured meat would involve approximately 7-45% lower energy use, 78-96% lower greenhouse gas emissions, 99% lower land use, and 82-96% lower water use depending on the type of meat.
The team point out that their calculations do not currently take into account additional savings from, for instance, the lower energy costs of transport and refrigeration of cultured meat compared to the conventional variety. They also suggest that land freed up from farming could be reforested or used for other carbon sequestration purposes, further lowering the carbon footprint of cultured meat.
