Play with your food. Break some rules!
We can search the web, go get a million recipe books, follow around a world class chef and huddle on to Mama's apron strings but one thing that will remain a rule in baking and cooking is: Break some rules! Play with your food!
Sure there are some hard and fast ones like: Yeast breads need yeast. Too much salt is pretty gross. But for many 'rules' there are acceptations.
Take things like altitude and humidity into consideration. A loaf of bread baked at 3500 feet above sea level will not be the same as one baked AT sea level. Tweak a recipe.
Most recipes are written for sea level and adjusted for differing altitudes. Don't let that keep you in a box though, break out of the rules of recipes and tweak. Just keep good notes (that's my downfall, I often play but forget what I did when it worked!).
Have fun. Learn by playing with your food.
Just be prepared to be VERY creative if it doesn't work out and not waste it by tossing it in the trash.
Best Blessings and enJOY learning more!
