Caramelised onions

Onions contain inulin, a substance that is converted into fructose, and which subsequently caramelises. This process gives the onions the ultimate umami taste, providing a perfect savoury element. The star anise further enhances this flavour. The preparation method presented here results in a maximum concentration of flavours. Although this method takes some time to complete, the result is sublime!
