Please try and get the basics right first...

...if you want to become a great cook...

I remember exactly when I cooked my first dish ever. I was at Uni in Algiers studying Computing and lived on the campus where food was not bad at all. If it ever happened to be a little bland then a generous dash of Harissa (North African hot sauce.) would give it a welcome zing.
I spent my weekends at my brother's who lived a couple miles away.
One weekend I decided to cook my mother's Lamb and Chickpea soup.
I phoned her for the recipe, bought all the ingredients with my meagre monthly allowance and Bob's your uncle, the result was delicious!
I then graduated to more elaborate dishes such as Tagines, Coq au Vin, etc...

But I really wish I had seen this video before embarking on my catering career...
