how long does it take for sausage to dry out so that it's more like salami?

Answer 1

I hang storebought pepperonis in my basement (cold room) for 2-4 weeks until they are all dried out and concentrated.

Make sure the sausages you use aren't fresh...they have to have been smoked or cured.

Answer 2

I don't think that's something you should do. I think sausage and salami have entirely different recipes and processes to make. I'd worry that experimenting with this might cause spoilage.
