*I usually heat the milk in the microwave for 1:30-2 minutes. If you overheat the milk, it will kill the yeast, rather than activating it. The milk should be mildly comfortable if on your skin-warmer than room temperature.
**I use alcohol free vanilla from Trader Joe's. It's the closest to pure vanilla bean and doesn't contain alcohol.
***when working with sticky dough, it helps to rub your hands down in vegetable oil so the dough doesn't stick to your hands. Instead of using flour to roll out the dough, use vegetable oil to prevent the dough from sticking and drying out. The additional flour used to roll out dough dries out the dough and changes texture when you need to reroll. Oil keeps the dough moist and pliable and prevents the dough from stiffening up.
