Stripey trumpeter hot and spicy soup

A hot and spicy soup is supposed to be a bit sour, a bit thin, and quite aromatic. This one is milder than some, because I wanted the sweetness of this incredible fresh stripey trumpeter to shine through. If you can’t get stripey trumpeter, other firm-fleshed, whitish fish, with big fillets, such as blue eye trevalla, or even a properly bled cocky salmon (a native fish, not the farmed version) will work nearly as well.
