Sure, go for it. I have had kool aid flavored pickles, I think they were quite the rage a couple years ago. Dump a packet in a jar of pickles, refrig until the color is bright red or green, and feed it to the kids.
Make apple sauce. You can take a handful of red hot cinammon candies and they will melt in the applesauce. Gives a bright color and spicy flavor.
Make apple butter. Either one in a crock pot. You can freeze or can them. We have lots of apples this year too.
Add mint to apple jelly. Tasty, but I think it has limited use. Add sliced jalapenos to jelly, leave the seeds in. Brush on your favorite grilled foods.
