Five Star Gift Ideas

That's great! Here are a few gift ideas for your grandpa who loves sourdough bread making:

1. Sourdough bread starter kit - you can gift your grandpa a sourdough bread starter kit that includes a sourdough starter, mixing bowl, measuring spoons, and recipe book. This will help him get started on his sourdough bread making journey.

2. Sourdough bread cookbook - if your grandpa is an experienced sourdough baker, you can gift him a sourdough bread cookbook which includes new recipes and ideas to experiment with.

3. Bread baking equipment - if your grandpa doesn't have the essential bread making equipment like bread pan, bench scraper, or a bread scoring tool, you can gift him those to make his baking process easier.

4. Bread-making class - you can also consider gifting your grandpa a bread-making class so that he can learn new techniques and gain some knowledge from professional bakers.

5. Quality baking ingredients - your grandpa would appreciate some high-quality flour or honey as a thoughtful addition to his sourdough bread-making ingredients.

Or you can get him a star map with an important date you share.
