我觉得宣传册上应该解释一下当地的便利店并没有卖一些像样的饼干，比如卡士达酱和姜汁饼干。

I think it should be explained in the brochure that the local convenience store does not sell proper biscuits like custard creams or ginger nuts.

你要不要来块姜汁饼干?。

Ginger and spice are not very nice.

我的一个同事喜欢吃姜汁饼干。

One of my colleagues likes to eat gingerbread nut .
