When I make the cucumber salad, I wash the cucumbers, peel them, and then rinse them off. Then I slice them on my food slicer. I'll take a slice from somewhere in the middle of the cucumber and give it a taste test. Even though the skin is gone, I'll still have a bitter tasting cucumber.
I know the cucumber skin can be very bitter, but even without the skin I can still taste bitterness in some of these cucumbers. I watched some more YouTube videos last night on the subject of bitter cucumbers, and I found a couple recipes that claim they will take out the bitterness of the cucumber by using a combination of vinegar and sugar in the mix. I'll try that with the bitter cucumber slices I set aside to see if corrects the bitterness. It's worth a try.
And, if I fail to correct the bitterness, I'll just throw the slices out into the chicken run. I bet the chickens will eat it without a problem. If not, at least it will get composted because I turned my chicken run into a composting system. I put almost all our organic material into the run and just let it compost in place.
