Wash and trim the tops off the guavas, then cut into segments.
In a large saucepan, combine the guavas, 3 cups of apple juice, brown sugar, cinnamon stick, cloves, and lime juice. Bring to a boil over medium-high heat.
Once boiling, reduce heat to a simmer and cook for 25-30 minutes until guavas are soft.
In a separate medium saucepan, heat olive oil over low heat. Add scallions, thyme leaves, Vidalia onion, and garlic. Sauté for 4-5 minutes until fragrant.
Add hot smoked paprika to the sautéed mixture and stir well.
Stir in tomato paste and cook for an additional 1-2 minutes, ensuring it doesn't burn.
Deglaze the pan with 1/2 cup apple juice and apple cider vinegar. Increase heat to bring to a boil.
Add black pepper, salt, molasses, chili sauce, and Worcestershire sauce. Stir to combine.
Reduce heat to a simmer and cook for 10 minutes.
Strain the guava mixture through a fine mesh strainer into the saucepan with the sauce base, pressing to extract as much liquid as possible. Discard solids.
Bring the combined sauce to a boil, then reduce to a simmer and cook for 35-40 minutes until thickened.
Use an immersion blender to puree the sauce until smooth. If using a traditional blender, allow the sauce to cool slightly before blending.
