for the cake:
for the glaze and decoration:
* Can substitute 235g (1 cup) unsweetened applesauce instead.
** Quince need to be cored a bit differently than other pome fruits (e.g., apples, pears, etc.). Split it open and use a small spoon (or measuring spoon/melon baller/corer) to scrape out the core and the stony area immediately surrounding the core. The core has the seeds and tough fibrous parts, but the area around the core also has some gritty bits, which you’ll want to eliminate. You can tell you’re done coring it once you no longer feel any rough gritty bits.
