What are some uses for homemade vinegar dregs?

I know you can add them to new vinegars to help start them. What else? I'll end up with a few litres by the time this year's vinegar frenzy is all bottled.

Maybe it would help to know what kind of vinegar you are making.

Something that I have read is to dehydrate it and throw it in soups and stews. This might not work for apples.

Try making raw dehydrated cookies or crackers.

Maybe use it as a topping this sounds good if it is fruit.
   
Then there is adding the dregs to bone broth.

I wonder if blending with olive oil and marinating meats with it would work.

Mixing the dregs into green smoothies.
 

Use the dregs to balance out alkaline soil, such as caliche, in composting projects. Or make Jan's Artisan Vinegar Dregs Hand Cleaner as a holiday gift for those permies working with high pH materials such as concrete or lime wash. Or grab an old tooth brush and some vinegar dregs to clean the limescale buildup on a spigot or toilet. Acid (vinegar dregs) + basic (calcium carbonate) leads to neutral pH.

I guess when I say dregs I actually mean the sediment of yeast and fruit pulp, in case that was confusing anyone.

Most of my vinegar still to bottle is elderberry, so I think using it to clean anything would be counterproductive 😆  It's a good idea for some of my other vinegars, though. And I like the hand cleaner idea. The local place I get my soap from series has high pH soap for really greasy work. I hadn't thought about a low pH cleaner.

Some of your food suggestions are intriguing, Anne. A vinegar cracker? Hmmmm....
