How to prevent bell peppers from being bitter.?
I presume that the bitter peppers you are referring to are
green. Bell peppers change from green to yellow, through orange
into red as they ripen. The red ones are far sweeter than the green
ones and green ones, by definition, are unripe. As you know, they
can be eaten when green and unripe but when they are too unripe,
they are bitter and taste unpleasant.
The best way of ripening them is to leave them on the plant to
ripen in the sun. This is fine if you grow them yourself. If you
buy them, either pick yellow or red peppers if the recipe allows
you to, or you can ripen the green ones a little once you have
bought them by storing them a while longer before using them. They
will not ripen enough to change color but they will be a little
less bitter. Hope this helps.
