If I was in her situation of having people from around the world sharing their culinary culture in my kitchen I would be integrating new found recipes and skills into the menu, just for myself let alone anyone else.
But hey, that's just me - we all have our different passions in life.
SJ tends to refer to Delia Smith and the BBC good food guide (which is pants btw. Often the recipes there are poorly put together and give poor results) She never seems to cross reference, develop and explore her own recipes. Probably why she bought the Thermomix. Blimey O'riley, that's an expensive bit of kit just to weigh and mix ingredients. It doesn't cook the food or even wash the dishes
I for one would NOT be interested in a La Lande cookbook. Dana K would be much better at this.
side note .. The Georgian Sunday vlog - she seemed to snatch the dumpling and proceed to fold it in a way that came across as I can do anything but she hadn't observed and took on board the way the dough needed to be centralised and how to tuck the folds by placing your thumb behind whilst turning it to create an enclosed tight parcel. It's the same technique that is used across Asia and would have been used in her kitchen when some of her volunteers made the 'worlds biggest dumpling'.
