I had been searching the WTMC website for the 2020 edition of the cookbook that I know exists but so far I had not been able to find it anywhere.
Now I have quite by chance come across it at the website tararuaphotos.com (sorry I don’t know how to put a link in this post).
The online version is interactive so you can click in the contents page and go straight to the recipe which is a nice feature. And it seems it should be downloadable as a pdf but I haven’t tried that yet.
Maybe the WTMC should make it easier to find on their website. Thanks
