In a bowl, combine chicken and 1 teaspoon salt, pepper, and cayenne pepper. Combine well. Bring a large saucepan to medium-high heat. Add 1 tablespoon of olive oil. Sear chicken in 3-4 batches until each side is golden brown. Add more olive oil when necessary.
Set chicken aside. In the same saucepan, lower the heat to medium. Add 1 tablespoon of olive oil. Saute shallots until soft and translucent, about 5 minutes. Add garlic and calabrian chili peppers and saute for 1 minute. Add in the cherry peppers and stir until well combined. Pour in the cherry pepper juice and white wine and simmer until reduced by half.
Add the can of crushed tomatoes and slowly bring to a simmer. Add the chicken back in and simmer for 20 minutes, stirring occasionally. Remove from the heat and stir in heavy cream until sauce is slightly pink.
Boil rigatoni until al dente. Combine rigatoni with the sauce while the pasta is still hot. Serve with parmesan cheese.
Notes
Every cherry pepper juice is different. Some are spicier than others. I always recommend tasting the juice with your fingertip before putting it into the sauce. The more juice you add the spicier it will be.
