I opened a 500 gramme tin of East End butter ghee about a year ago.
It's got a resealable platic lid.
I keep it in my larder (I live in an old house) and it's still fine
I reckon most tubs of ghee, I got, have been thrown away with only a fraction used.
I get a recipe needing a tablespoon, then don't use it again for a couple of months.
I did find a few pastry recipes with it
They were very nice, but all deep fried!!
Not so good for you
