Mix fresh lemon juice into cashew butter with some stevia extract powder.
Dip apples in it.
Tip: Every nut butter and also chocolate… will get much thicker when you add a small bit of water. This is what makes chocolate “seize up”. With nut butter, if you keep adding more liquid, it will get past the point where the fiber absorbs all the water and the extra water will then begin to loosen the mixture so it becomes more “watery.” So, the *ratio of water-to-nut-butter is the important thing in getting the correct consistency. If it seizes up, just keep adding a little bit more liquid at a time until you get the consistency you want.
