If the thread exists, one thing I would suggest, is for a food manufacturer to ask if people would be interested in sachets of purée food of the same quality and lack of lumps as for 4 month old babies, yet not intended for babies and labelled as for adults, but of recipes that adults may appreciate but which would not be suitable for babies. For example, containing onion, tomato, maybe spices, and so on.
A lady on a care line told me that they are aware that a lot of their baby food is in fact eaten by adults.
So a niche product for a manufacturer, yet sometimes a niche product can produce amazing results for a business as there is so little competition for supplying their product.
And no, I am not suggesting it would be their only product range.
