One gift idea for your husband could be a home fermentation kit. There are many different types available, ranging from kombucha and beer making kits to kimchi and sauerkraut fermentation kits. You could also consider adding in some specialized fermentation tools, such as an airlock or fermentation weights.
Another idea might be a cookbook focused on fermentation, such as Sandor Katz's "The Art of Fermentation." This would allow your husband to explore new recipes and techniques and expand his knowledge of the fermentation process.
Finally, if your husband enjoys learning or exploring new hobbies, you could consider signing him up for a fermentation class or workshop. Many local food co-ops or community centers offer workshops on fermentation, where he can learn about different techniques and connect with fellow fermentation enthusiasts.
Or you can get him a star map with the date when he was born.
