I agree with you that immediately after eating bitter leaf soup, when you drink water, it will turn to sweet taste. I love it too and like you said, it needs a lot of water to wash off the bitterness.

As for the pepper, its very simple:

Just prepare the group or put fertile sand in a bowel that you are not using again, through the seeds in there and water it.

Once the nursery sprouts, til the ground, add water, chicken manure and ash. Then transplant and make sure you water regularly if there is no rain. Apply that manure from time to time once you notice that the one you applied is fading away. And wash it surprise you. Try it out and give me update let's follow up on it.
