篇6：酸辣粉怎么做酸辣粉各食材的处理方法（图）

- 准备食材 -

红薯粉

香菜

蒜泥

酥香黄豆

熟花生米

浓汤宝

葱末

熟芝麻

辣椒油

麻油

白糖

盐

胡椒粉

花椒粉

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}” onclick=“if(!this.resized) {return true;} else {window.open('/Article/UploadFiles/200602/200693061740846.jpg');}” src=“/Article/UploadFiles/200602/200693061740842.jpg” nload=“if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}” border=0>

选择图层样式

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}“ onclick=”if(!this.resized) {return true;} else {window.open('/Article/UploadFiles/200602/200693061740630.jpg');}“ src=”/Article/UploadFiles/200602/200693061740987.jpg“ nload=”if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}“ border=0>

调整如图

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}” onclick=“if(!this.resized) {return true;} else {window.open('/Article/UploadFiles/200602/200693061740919.jpg');}” src=“/Article/UploadFiles/200602/200693061740304.jpg” nload=“if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}” border=0>

隐藏背景层的眼睛，

screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor='hand'; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}“ onclick=”if(!this.resized) {return true;} else {window.open('/Article/UploadFiles/200602/200693061740725.jpg');}“ src=”/Article/UploadFiles/200602/200693061740982.jpg“ nload=”if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window\\nCTRL+Mouse wheel to zoom in/out';}\" border=0>
