If the far right peppers are cayenne and hot, try a pepper sauce.

I used chiltepin, wild pepper, with this recipe https://ourdailybrine.com/southern-pepper-sauce-recipe/ was great on eggs or in bean soup to give it a kick.

Or try a hot sauce like Frank’s https://www.chilipeppermadness.com/recipes/cayenne-pepper-sauce/

If bottom left are scotch bonnet try Jamaican jerked chicken https://www.chilipeppermadness.com/recipes/jamaican-jerk-chicken/

And pickling them is always good especially with the mild ones, orange sweet peppers I’d assume.
