How to Prevent Cookies From Spreading
Here are some helpful tips to prevent cookies from spreading:
不要过分击球
Far too many recipes advise bakers to simply“Cream butter and sugar until smooth”。So many people just turn on the mixer and go check their e-mail.
When you beat butter and sugar, those little crystals of sugar create air pockets between the butterfat. The more you beat, the more air you incorporate (those trapped air pockets steam open and expand in the oven). That’s great for a nice, light cake…but not for most cookies. So when the recipe says, ““奶油或搅拌黄油和糖”, just mix them for about 30 seconds, until well-combined.
Use Ungreased Baking Sheets
Unless the recipe says so, bake cookies on an ungreased or unbuttered baking sheet. You’re creating a slippery surface if you do, which causes cookies dough to slide. I use parchment paper, which has just enough friction for cookies to stay-put without sliding around, but they don’t stick.
正确测量成分
我知道这很大duh!, but adding more liquid or less flour than a recipe indicates makes a big difference. When people tell me,“I can’t bake”, I never understand that. I mean, how difficult is “8 ounces of butter” or “3 large eggs”? It’s not like a piece of meat that you need to guess and adjust cooking times. Baking is a no-brainer.
也不要更改成分。使用超大鸡蛋代替大鸡蛋意味着您添加了更多液体。除了使用通用面粉（或需要使用的任何东西）以外的任何东西也可能是有问题的。
Check Your Fat
大多数黄油大约是80％的脂肪，这意味着其余的大约为20％的水。当在面糊中使用时，水液化和voila!。You can use a ‘European-style’ butter, which has a higher percentage of fat and remains more stable when baked. Examples of this include插头。
Some recipes use vegetable shortening instead of butter, which is another alternative (although I don’t personally use vegetable shortening). Vegetable shortening is 100% percent fat, which means there’s little water so things stay in place better when baked (it’s why pie dough made with shortening is flakier…there’s little water to saturate and toughen the flour.)
如果您选择用蔬菜缩短代替食谱中的黄油，请找到无反脂肪的一种，现在可以使用。
检查烤箱温度
每个烤箱都是完全不同的。我有一个晚上晚上11点打电话给我，告诉我她的花生酱饼干花了10分钟的时间烘烤而不是9分钟，如食谱所示。购买烤箱温度计并检查烤箱的准确性。
如果您将饼干放在不够热的烤箱中，它们会在突然之前下垂并散开。
