Broad bean question!!

[Thankyouandgoodnight]

I cooked some frozen broad beans (simmer for 1 minute) as per my recipe instruction and then squeezed the bean out of the skin. I love broad beans but these taste quite bitter - is it because they weren't cooked for long enough?

could be they cooked for too long.
i just pour boiling water over frozen broad beans and then pod them.
Think of them as sweet new peas and don't boil for hours.
