I would recommend, maybe through interlibrary loan--if not buying, the book Wild Fermentation. It has mostly fermentation recipes, but some which combine sprouting with fermenting.
For instance an easy-enough recipe which calls for sprouting grains, then food processing, then adding a sour dough culture to make probably a rather easily digested bread.
There are also instructions for nearly every fermented food you can think of. The next one I want to try is culturing a "ginger beer plant". This actually involves combining a cup of boiled water with a tsp of sugar. When that is dissolved/cooled down to room temp, you add a tsp of grated fresh ginger (including grated brown skin of ginger for beneficial microbes). Then, you just let this sit out for a few days and add the 1:1tsp sugar/ginger till a bubbly/slimy fermentation is apparent. From there, you use this as a starter for a large batch of ginger/sugar/water to create authentic ginger ale in bottles. However, this may take longer than they let on. At least two, probably 3/4 weeks.
