Nut oil longevity?
How long would you say hazelnut and walnut oil last in cans that have been refrigerated since opening?
I have some hazelnut oil from last year that I have kept in the fridge...tasted it recently and it seems good. Most of the recipes that I use it for are Autumn types of dishes, and I just did not use it at all over the summer, so I am glad I can still use it and don't have to get another bottle.
The sure way to tell is just to taste it, a little bit by itself on a spoon.
Walnut oil always seems to go rancid before I can use it all , so I have not even bought any for a long time, I don't even buy walnuts in bulk any more, just what I know I will use in a week....Fresh walnuts are showing up from this season in the Farmers markets here...
I have had a jar of Macadamia nut oil in the fridge for 3 years, and it still smells/tastes great. (I keep my fridge pretty darn cold).
