Ever since I started cooking I’ve been fascinated by how different people’s techniques are and how they best utilise the ingredients around them. Even the person living next door will have their own unique way of frying an egg or cooking a salmon fillet.

This fascination led me on a journey across the globe to discover the countless practices and traditions the world of cooking has to offer. I thought you’d enjoy and find value in sharing that journey with me so I created Cooked Best!
