One gift idea could be a sourdough bread making kit. This could include a sourdough starter, a bread bowl, bread flour, and a bread lame for shaping the dough.
Another idea could be a sourdough bread cookbook, such as "Flour Water Salt Yeast" by Ken Forkish or "Tartine Bread" by Chad Robertson.
If your friend already has these items, you could consider gifting unique bread baking tools such as a banneton basket, a dutch oven, or a bread scoring stencil.
Finally, you could organize a sourdough bread making workshop or attend one together as a gift.
Or you can get her/him a star map with an important date you share.
