Thickening Apple Butter

I cook mine in a roaster in the oven for several hours and it thickens on its own by cooking out the excess liquid.

I've just made two batches this past Fall for the first time--the best way to thicken it is to just put the pot or crockpot at it's lowest heat, UNCOVER (I noticed the other posts don't say this!) and continue cooking, stirring once in awhile. A few hours more cooking will let the water/steam out, which will naturally thicken the apple butter. Good luck!

You can try cooking it at a lower heat or in a crock pot. Also try adding some cornstarch.

Thanks everyone for your advice.

Cornstarch will work, or you can let it thicken with the apple's natural thickener, pectin. Just continue to cook the butter slowly and stir constantly.

My crockpot has a removable crock. The easiest way to thicken apple butter is to put it in the crock in a 350º oven without a lid. Stir it occasionally until it is as thick as you like it.

I think maybe the apple butter needs to be reduced more...cooked longer.

I put mine in the crockpot and let it cook until it is thick. It takes a while but it works.

maybe cornstarch? or additional apples
