In a medium pot over medium heat, melt 2 tablespoons of butter and add 6 ounces of tomato paste along with salt and pepper. Stir frequently for about 5-7 minutes until the mixture darkens and caramelizes, releasing a rich aroma.

Carefully pour in 4 cups of beef broth and add 1 tablespoon of sugar, stirring well to combine. Bring the mixture to a gentle boil over medium-high heat, which should take about 3-5 minutes.

Stir in 1 cup of Anellini pasta to the pot, ensuring it's fully immersed in the flavorful broth. Reduce the heat to medium and cover the pot, cooking according to the pasta package instructions, typically about 8-10 minutes.

Once the pasta is cooked, turn off the heat and sprinkle in ½ cup of grated Parmesan cheese. Stir vigorously until the cheese melts and creates a creamy consistency.

Taste the dish before serving, adjusting seasoning as needed with more salt or broth for desired consistency.
