Heat a large saute pan and add oil. When oil starts to lightly smoke, add the pancetta. When pancetta is half crisped, add shallots and onions and lower the heat, carefully cooking so they don't burn.
When onions are translucent, add garlic. Cook for 30 seconds, and deglaze with red wine. Add the Marinara Sauce, stock, and basil, then cook until reduction thickens. Add cream, Gorgonzola, and Parmesan, and cook until cheese is incorporated. Add salt and pepper, to taste. Add warm penne rigate and toss. Serve in very warm bowls and top with coarsely grated Parmesan and garnish with thyme sprig.
Roughly chop celery, onion, and carrot. Sweat in olive oil until onion is translucent. Add garlic and cook for 2 minutes, then incorporate the tomatoes, sambol, basil, thyme, and stock. Simmer uncovered for approximately 2 hours until stock reduces and mixture thickens. Blend in a food processor until texture is smooth. Adjust seasonings with salt and pepper, to taste.
