[Recipe] Instant Pot fish stock

This Instant Pot fish stock is simple to make and is packed with flavour using salmon heads and lemon grass for the subtle citrusy flavour. Lightly pan frying the fish heads will help bring more flavour to the soup and many times helps to keep the fish meat from staying together more in the pot during the cooking process.

With the pressure cooker, the flavour of the stock is amplified and is super easy to use. For those who say they don’t have time to make homemade stock, get yourself a pressure cooker. In less than an hour, not hours, you can get amazing stock.

The recipe can be  can be made on the stove top in a regular pot with a longer simmering time. I find with fish stock, it doesn’t need much time to extract the flavour compared to making chicken or pork bone broth.

I have used salmon for the fish stock, but feel free to substitute based on what is available at the fish market. Add in fish bones if they are available.
