There won't be an Experimental Cookery post this week. I was intending to do something from one of Gordon Ramsay's books (this being the only cookbook I own that I have not yet used). Unfortunately, the recipe calls for both mango powder and coconut oil, neither of which I have been able to source.
This is actually something that has annoyed me in the past: cook books do tend to require the occasional 'obscure' ingredient, not easily sourced from the supermarket, and they also tend to be quite poor in either identifying a substitute, or at least indicating where they believe you could source the ingredient. It's most vexing, as it can render large parts of the book unusable.
