Are these worth keeping?/recipes(Carolina reaper)

My Carolina reaper, died from the cold last night. I picked all the good looking ones today, there are a number of small green ones that I am not hopeful for, but I am hopeful for the orange one and the large green ones. I am going for only spice.
If there are ways to ripen off the plant, I don’t know.
I would prefer a powder or something I could sprinkle on food to get the spice.
Just generally help me know what to keep, and what to do with them, thank you.
