My Onions Have Turned Blue

[NiceWelshLady]

I am boiling onions with garlic to make a stew, something I have done regularly for years. This time for some reason the onions (or possibly the garlic) has turned a greeny blue colour.

The pot and spoon were completely clean before I started, so it's definitely not contamination. Has anyone else had this happen? I've chopped 20 onions and 20 cloves of garlic, so I will be mightily displeased if I have to discard the lot.

Thanks 😊

It's fine. I've looked it up before it's some chemical reaction which I can't quite understand but it's definitely edible.

Thank you. That's a relief... 🥵

Accidental blue soup managed to help Bridget Jones to bag Mr Darcy so I hope your blue stew is just as successful :)
