Bring a large pot of well-salted water to a boil and cook the penne until al dente. Drain and give the pasta a quick rinse with warm water. This step is unique to Flower Chef pasta and helps remove excess surface starch so the sauce coats the noodles cleanly and evenly. Set aside, reserving a small cup of the cooking water.
In a large pan, warm the olive oil over medium heat. Add the shallot and garlic and cook gently until soft and fragrant, without browning.
Stir in the tomato paste and cook for 2–3 minutes, letting it deepen in color and caramelize slightly. Add the vodka and simmer for 3–4 minutes, allowing the alcohol to cook off and the sauce to smooth out.
Lower the heat and stir in the cashew cream. Let it warm slowly until silky. Season with salt, pepper, sugar, and chili flakes to taste.
Add the penne directly to the sauce and toss to coat. Use a splash of the reserved cooking water if needed to bring everything together.
Finish with fresh herbs and a drizzle of good olive oil. Serve immediately.
Notes
Vodka helps mellow the acidity of tomato paste and brings out aromas that water alone can’t unlock, creating a sauce that’s smoother, rounder, and more balanced.
