FAQ

Can I use turkey sausage instead of pork sausage?

Yes, turkey smoked sausage works well and will reduce the fat content while maintaining the smoky flavor profile.

What if I don't have a food processor for the peppers?

You can mash the peppers with a fork for a chunkier texture, or use an immersion blender directly in the jar.

How long will leftovers keep in the refrigerator?

Properly stored leftovers will keep for up to 3 days. Reheat gently with a splash of cream or pasta water to restore creaminess.
