The article highlights the revival of the UK and Irish truffle industries, with the harvest of the UK's first cultivated truffle in 2015 and the first in Ireland in 2022.

The article also discusses the potential benefits of climate change for truffle production in the UK, such as the growth of Périgord truffles in Wales due to increased temperatures.
