Plain butter

素黄油───Plain butter

Waiter: Would you like butter or jam on your toast or you just want it plain?───服务员：吐司上抹黄油或者果酱还是什么也不要？

Plain butter cannot be heated to the required temperature without burning.───普通的黄油不行，因为还没等加热到所需的温度它就要烧起来啦。

Sift together the plain flour, cornstarch and cocoa powder together into a separate bowl. Add half of the flour mixture to the butter mixture and beat on low speed until just combined.───筛面粉、米粉和可可粉到一个碗里，加一半的面粉混合物到黄油混合物，低速拍打完全混合。
