Class Experience

Students will learn about the principles of steam energy; about how steam energy is used in baking; and they will learn how to make clarified butter and how to use it to make natural, stove top, butter popcorn that doesn't burn.
We will also be making a flaky pastry crust.  We won't roll it out in class, but it will be ready to roll shortly after class, and a video will be provided with tips on rolling, filling, and crimping.
I began learning classic cooking techniques from my mother when I was a child, and that began a life-long love of classic, basic cooking.  At this point I am very experienced and knowledgeable cook, and I am passionate about science.  I regularly make stove top popcorn, pastries, and many other interesting dishes.  
No homework

3 cups flour
1 cup butter, cold
1/4 tsp salt ( or more if you are using unsalted butter)
1 cup water
Plastic wrap that you can use to lay out several layers
Large mixing bowl, measuring cups, table fork, and two knives ( or hand pastry blender and counter knife if you have those)

1/4 cup butter
1/4 cup popcorn (any kind--air pop, does't matter)
Small metal bowl or other heat-proof bowl (hot butter will get poured into it)
3 quart saucepan with LID
1 hour per week in class, and maybe some time outside of class.
Making this popcorn involves high heat and handling heated oil (clarified butter).  I ask that parents make a careful decision about allowing their student to make this during class.  The oil (including butter fat) gets very hot and could potentially cause burns.  Cooking in the home should only be done with parental permission according to the rules of your home.  Parents are welcome and encouraged to be a support to their child during class.
