Tasty,
Cooking "free style" is something that happens as you get experience. Fifty years ago, as a new bride, I usually followed recipes to the letter and sometimes they didn't turn out and that too was a lesson that added to my "book of food knowledge."
I've always been very outgoing and never afraid to approach strangers in grocery stores who were purchasing something with which I was unfamiliar. In some cases I made life-long friends who had a similar interest in food.
I learned to cook many ethnic dishes in this manner and was introduced to some extraordinary people.
Now, with the internet, this is so much easier and the immensely wider availability of "exotic" foods makes adventurous dining a wonderful possibility.
