01 - Cook the fettuccine or linguine according to package directions until perfectly al dente. Drain thoroughly and set aside.
02 - Gently heat the whole milk in a small saucepan until it is steaming but not boiling. Add the tea bags and 1 tablespoon of brown sugar. Allow to steep for 5–7 minutes, then remove and discard the tea bags.
03 - In a large skillet over medium heat, melt the unsalted butter. Add the minced garlic and sauté for approximately 1 minute until its aroma intensifies. Pour in the heavy cream and bring the mixture to a gentle simmer.
04 - Introduce the steeped milk tea into the skillet with the cream mixture. Stir gently to ensure a homogeneous blend. Allow this to simmer for 2–3 minutes, enabling the flavors to meld harmoniously.
05 - Incorporate the grated Parmesan cheese, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper into the skillet. Stir continuously until the cheese is completely melted and the sauce achieves a smooth, luscious consistency.
06 - Add the cooked pasta to the skillet containing the Alfredo sauce. Toss gently to ensure every strand of pasta is evenly coated. Continue to simmer for an additional 2 minutes, allowing the sauce to thicken and adhere elegantly to the pasta.
07 - In a separate saucepan, bring 2 cups of water to a rolling boil. Add the black tapioca pearls and cook according to the manufacturer's instructions, typically 3–5 minutes. Drain the cooked boba pearls and immediately toss them with 2 tablespoons of brown sugar.
08 - Portion the milk tea Alfredo pasta onto serving plates. Garnish each portion generously with the prepared sweet boba pearls.
