Combine all of the ingredients (besides the salmon!) in a blender and whizz to a paste – it’ll be quite liquid-y.
Place the salmon on a baking tray. Rub a little of the beetroot cure into the skin then place the fish skin down in the tray.
Pour the rest of the cure all over the salmon and use your hands to press as much of it into the flesh as possible.
Cover the tray with clingfilm and place another tray with a weight on it on top to press down onto the salmon.
Store in the fridge for 48 hours.
After curing for two days, pour the liquid from the tray and use your hands to scrape away the cure from the flesh and skin of the salmon. Use kitchen paper to further wipe away any of the curing mix.
Now it’s ready to use! You can cut away thin slices on a slight angle along the length of the flesh.
To store, press some fresh dill into the flesh and tightly cover with clingfilm. You can store this for up to a couple of weeks.
