One idea could be to get him a sourdough bread making kit. This could include a sourdough bread recipe book, along with a sourdough starter culture and any bread-making tools that he may not already have. Additionally, you could purchase a bread baking stone or a Dutch oven to help him create the perfect crust on his sourdough loaves. Another option could be to find a local class or workshop on sourdough bread baking that he can attend, so that he can continue to build his skills and knowledge in this area.
Or you can get him a star map with an important date you share.
