Quince Paste

Gather the ingredients.

Wash and peel the quinces, reserving the peels. Core the quinces, adding the cores to the reserved peels. Chop the remaining quince into approximately 2-inch chunks.

Tie the peels and cores up in cheesecloth or in a clean muslin bag.

Put the chunks of quince and the bundle of peels and cores into a large pot. Add water to cover by approximately 1 inch. Bring to a boil over high heat. Reduce heat and simmer for 1 to 1 1/2 hours, or until the quince chunks are mushy-soft.

Remove and discard the bundle of peels and cores. Strain the remaining cooked quince through a very fine-meshed strainer or a double layer of cheesecloth set in a colander (you can use the liquid that strains out to make quince jelly). Leave the quince to strain for 2 hours.

Puree the strained quince mash in a food processor or run through a food mill.

Weigh or measure the puree then put it in a large pot. Add an equal amount by weight or volume of granulated sugar.

Cook over low heat until very thick, approximately 1 1/2 hours. Stir constantly at first to dissolve the sugar, frequently after that. When it is done the quince paste will stick to a wooden spoon, and if you drag the spoon over the bottom of the pot it will leave a trail that does not fill in immediately with the quince. Be careful at the end of the cooking time to stir often and not let it burn.

Lightly grease a 9-inch baking dish. Spread the quince paste in the dish smoothing it out with the back of a spoon. It should be about 1 1/2-inches thick. Let the paste cool in the baking dish.

Dry the paste in your oven at the lowest setting, not higher than 125 F / 52 C. If your oven doesn't go this low, use the lowest setting and prop the door open with a dishtowel or the handle of a wooden spoon.

Alternatively, remove all but the bottom tray from your food dehydrator. Place the baking dish of quince paste on the bottom tray and set the temperature to 125 F / 52 C.

Dry the quince paste for 8 hours or overnight. The surface should be glossy and not sticky to the touch. Put the baking dish of quince paste into the refrigerator for 4 hours.

Run a knife around the edges of the paste. Invert the quince paste onto a plate. Slice as desired. Wrap in plastic wrap and store in the refrigerator for up to 3 months.
