In the fall I'm always looking for Quince but seldom find them. Quince is a green fruit grown on a bush in most areas. It keeps well but is seldom found in stores. Walmart sometimes has them.
I use them in Apple pies - they make the pie a little buttery. I have also made Quince liquor in the past when I find them. It is a very good and light tasting liquor. I put a couple of Allspice berries in the liquor with the Quince and 100 proof Vodka. Let them sit for a month in the dark, after that month screen the liquid to remove the solids. Make simple syrup out of sugar or honey or both, add enough sweening that you like (I don't add a lot but most people do) and then take clean water and reduce it to 40 proof and then put it back in the dark for another month for the flavors to combine. You have a great liquor - if you can find quince, that is! I do the same with cranberry, blueberrys you have to freeze, put them in something to break them into pieces frozen, add the Vodka and set them in the dark three months. Then add simple sugar and dilute to 40 proof.
There are several books available on how to make liquors - if you are interested. When I make an apple pie I take the skins of the apples, remove the seeds and add the cores, and make a liquor of that. That one I will often spice up. When we have a mango I will take the skin and the seed and do the same thing.
