There's a discussion about persimmons on the general board.
A local tv show just made a guacamole with persimmons. Not sure if that would be a good combo, but it surprisingly looked pretty.
2 ripe avocados, pits removed, flesh scooped out with a large spoon, put face down on a plate
1/4 cup red onions, finely chopped
1 Fuyu persimmon, peeled, pitted and cut into 1/4 inch dice
1 large clove garlic, minced
1 chipotle in adobo, seeded and minced + 2 teaspoons of the adobo sauce
2 teaspoons lime juice
2 Tablespoons olive oil
1/4 cup cilantro, chopped
1 teaspoon kosher salt
And to restate the instructions, uh ... mash avacado and mix in all else.
Here's a few past links on persimmon recipes on Chowhound.

Kind of surpised there's only one persimmon recipe on Chow, but maybe in the future this will link to more.
