Heat cherry tomatoes in olive oil over medium-high heat until their skins blister and burst naturally—this concentrates their sweetness and creates the flavorful base for your sauce, rather than crushing them immediately.

Mix ricotta with reserved pasta water before adding to the sauce to loosen its texture and prevent clumping, creating an ultra-silky, cohesive coating that clings beautifully to the pasta.

Cook tomato paste in olive oil for 1-2 minutes before adding other ingredients to deepen its flavor and remove any metallic taste, resulting in a richer, more complex sauce.

Add heavy cream off-heat or at a low simmer to prevent it from breaking; if your sauce seems too thin, reduce it gently over medium-low heat rather than boiling aggressively.

Save at least 1 cup of starchy pasta water before draining—this liquid is crucial for emulsifying the cheeses and cream into a luxurious sauce that coats the noodles evenly.
