a sweet and soft, but firm, food that you can cut, made from quinces (= hard fruit that look like apples) cooked with sugar

The quince is now making a comeback, not so much as sweet jelly, but as quince paste to accompany cheese, also known as membrillo. 现在榅桲又卷土重来，不再作为甜果冻，而是作为榅桲酱来搭配奶酪，榅桲酱又叫“membrillo”。

We paid $4 for some thin blocks of quince paste. 我们花四美元买了一些薄块的榅桲酱。
