can I use defrosted peppers to make hot sauce?

[habitat_gardener]

I had some mildly hot peppers that were in the freezer so that we could add a small piece at a time while cooking. Unofrtunately, my partner did not return the container to the freezer. I now have a container of defrosted peppers that are too hot for us to eat in one meal, and I was wondering if it'd be safe to buzz them in the food processor with some vinegar to make some hot sauce. Or other ideas?
