But I already mentioned lime or lemon juice in my article.
Apologies - see, I neglected to actually read the linked column and thought I’d pipe in with something useful (it’s not something I get to do often 'round these parts, so I grab every opportunity!).
A few drops of lemon juice in your avacado mash will keep it a lovely green for hours.
Ignore ignore ignore. :doh:
Tried to cancel, failed. I am bad.
