In a presence of a looming winter I make simple compote.
Quarter the quinces and put them in a large bowl. Cover with water and bring to a boil. Turn the heat down and simmer until fruit is soft (at least 30-40 minutes). When they are cooked trough, serve them warm or at room temperature.
No sugar, no spices, just simple pleasure of cooked quince flesh.
Advice: use sharp paring knife and be very careful when cutting the quince.
