It's been a few days since I posted a length of white mohair and onions.
This is what it was about.
Don't need the old recipe book in the background.
Or the bottle of beer............
You do need plenty of onion skins. (just the skin)
More you have, deeper the colour.
A pan of boiling hot water.
Try 10 cups (English, American, doesn't matter (or ten mugs).
Add the onion skins, after you have stopped crying.
15 minutes and the colour of the water should look something like this after you have strained out the onion skins.
You can use red onion skins colour will look just as good.
