How about a DIY fruit preserving kit? You could get some mason jars, lids, and any necessary tools and ingredients for the type of fruit preserves he likes to make. You could also include a book on different recipes and techniques for fruit preserving. Another idea is to find a local class or workshop where he can learn more about fruit preserving techniques and try out new recipes. Additionally, you could find a high-quality jam or preserves from a local artisan or specialty shop that he may enjoy.
Or you can get him a star map with the date of your anniversary.
