Cooking with papaya seeds - what does heating them do?

I’ve got a bunch of papaya seeds left over from a ripe fresh papaya and I’m trying to work out what I can do with them.

Researching this comes up with precisely two types of page:

• Hundreds of dubious articles claiming miraculous health benefits (I’m skeptical, but good to know they’re edible)
• Hundreds of recipes for salad dressing, based on putting them cold in vinegar. I’m not especially interested in salad dressing, but if the vinegar does anything interesting to the seeds that could be used in other ways, that would be good to know about

What effect if any does cooking them have? Are they edible cooked? Are there any particular ways of heating them or ingredients to cook them with that bring out or modify their flavour in any notable way?

Cold, they’re kinda tangy, sharp, bitter, not unlike peppercorns but more bitter and maybe slightly citrus-y. They seem to get more bitter the longer they’re off the fruit – after two days in the fridge my stash became obscenely bitter, just one seed and I could still taste the bitterness 5 minutes later.

Or any other methods of preparation? Does steeping in vinegar do anything interesting? Or any other liquids? Crushing, freezing? Anything?
