What's your secret ingredient that makes your version of a common dish better than anyone else's?
Mine probably isn't that secret these days, but almost every sauce I add nutritional yeast to. Curry, chilli, bolognese, it just makes them all better.
Last year I picked a huge amount of mushrooms in the forest, dehydrated them (you can buy a dehydrator or use an oven) and ground them to a powder.
I put mushroom powder in damn near everything I cook, gives it a nice hit of umami.
