Description 低筋粉 180克；瘤奶 120克；糖粉 90克；莓干 60克；羽兽卵液 22克；盐 1克 虽然是最基础的饼干，但是古米很喜欢吃。 瘤奶放至室温加入糖粉，拌匀后加入羽兽卵液。莓干需要切成小片，整颗莓干口感略酸。低筋粉过筛加入，揉匀后修整成切面长宽均4厘米左右的长块。 备注：若给索尼娅需要做更大些。娜塔莉娅喜欢吃多加些盐的。罗莎琳的要淋上蜂蜜。 放入冰箱冷冻1小时，取出切片，放入预热170度的烤箱20分钟即可完成。 ...... 原来是这样......我竟然一直以为这位上司就是最后的幕后黑手！现在再回翻以前的描述，他确实做了很多他原本不会做的事。如此明显地放过打探消息的主角、在大会上那样真心地宣誓，还有他与他夫人竟是真心相爱，而不是政治联姻......他竟然以自杀作为开端...... 虽然有作者故意设计出的叙述诡计的影响，但我确实因为一种先入为主的无意识忽略了很多不寻常的细节。 人们或许真的会在某种特定的环境下被各方信息所影响，忽视掉一些原本很明显的信息。 我确实忽视过很多。 这也是我在以后需要时常反思的地方。 ...... 在罗德岛这些日子，我向博士借阅了许多书籍。作为一名学生，我确实经历了大多数同龄人不曾经历过的事情。以我现在的知识水平，书中提到的一些问题我并不能深刻地理解，只是有了这段经历，我或许能感受到作者的意图。 正如《深林》这本书中关于“群体性”的一段：“做过一次坏事的人发现自己不会受到惩罚，因为周围知道这件事的人选择视而不见，继续过着自己的‘好日子’，所以他们才会去做第二次第三次。只要有人愿意死盯着，喊出声来，这片混沌就能被破开。” 只要有人愿意死盯着，喊出声来，这片混沌就能被破开。 ——节选自真理的读书笔记
