Why did quince not turn pink when cooked?
The tannin concentration in a quince, which varies depending on where it’s grown, determines this color: Heat causes tannins to release a red pigment called anthocyanin. Quinces that are rich in tannins become dark rose; those with fewer tannins may remain creamy white or turn light pink.
