How many days sardine butter last in the fridge. Recipe says quite a while. Please be more specific.
I would imagine it would be fine for at least a week, and you could certainly make it ahead and freeze it if you wanted it to last for a VERY long time. How long do you need it to last?
We continued to eat it a week after I made it, although it does tend to lose some of it's flavor the longer you keep it around.
