Preheat your oven to 350 and gather together your baking ingredients and materials.
Puree the salmon (undrained – include the packing liquid) in a food processor or similar. Transfer to a mixing bowl.
Add ground flax and optional herbs. Stir to combine.
Incrementally add flour to form a nice firm workable dough. Tinned salmon can vary quite a bit in consistency and in liquid content, so working incrementally is important. You may need to use less/more flour to adjust consistency depending on your specific ingredients and prep methods. You can add a bit of water if you find the mix a bit too dry when you are ready to roll.
Rest dough (optional but recommended). Adjust consistency for rolling after resting, if needed.
Roll, cut to shape, and place on a prepared baking sheet.
Bake for approximately 10-15 minutes (less if you’re making tiny treats). Keep an eye on your cooking time – the smaller the treat, the shorter the baking time. For a crunchier treat, you can let baked treats sit a while in the cooling oven before removing to get a little crispier or pop the baked treats into a dehydrator.
Allow to cool before storage and serving.
