Can you smell the ginkgo? No? Consider yourself lucky!
Actually, despite the putrid smell of ripe ginkgo fruit, many (myself included) anticipate their arrival every fall. Come October I stuff my pockets full of latex gloves and plastic grocery bags and wander the streets and parks of New York City breathing deeply, searching for female ginkgo trees.
The ripe fruit really DO smell like cheesy vomit (I don't mince words) but the nut inside the fruit is an under-appreciated delicacy in the US of A. If you get a whiff of something putrescent as you're walking down the street, look up.
Put on those latex gloves and pinch the fruit to squeeze out the kernel inside. This is what you'll be taking home with you. (The first time I foraged for ginkgo I made the mistake of bringing the whole fruit home. That stench fills up a studio apartment mighty fast, let me tell you!) When you get your harvest back to the kitchen, run the nuts under water to get off the last shreds of smelly flesh. Then, spread them on a cookie sheet and roast for an hour at 350 degrees.
Once the nuts have been roasted, place them between two dish towels and tap with a hammer. After destroying a few, you’ll get a feel for how hard to hit without shattering the nuts.

Ginkgo pesto
In a food processor, combine 1 cup roasted, shelled gingko nuts with 1 Tbs. olive oil and 1 cup fresh basil leaves. (Yes, the end of basil season overlaps with ginkgo season.) Pulse until the mixture is a coarse paste (adding more oil if necessary), then season with salt and pepper to taste. You won’t need cheese; the ginkgo nuts do double duty in this recipe. The pesto keeps in the refrigerator for up to a month. At room temperature the oil may separate, so be sure to stir well before using.
