Ultimate Alfredo Sauce

Collect all necessary components for preparation.

Heat the butter and olive oil in a saucepan over a moderate-low heat setting. Melt these two ingredients together until they reach a liquid state, then add the cream, garlic, and white pepper to the saucepan. Stir gently until the mixture starts to bubble, then lower the heat and let it simmer, stirring constantly, until the liquid has slightly decreased in volume, taking approximately 5 minutes to achieve this effect.

Add the Parmesan cheese to the cream mixture and continue to simmer until the sauce has thickened into a smooth, velvety consistency, which should take around 8 to 10 minutes.

Next, incorporate the mozzarella cheese into the sauce and cook until it has fully melted, stirring constantly to prevent lumps from forming. This process should take about 5 minutes.

Meanwhile, bring a large quantity of salted water to a rolling boil in a separate pot. Add the pasta to the boiling water and stir occasionally until it reaches the desired level of doneness, still retaining a slight firmness to the bite. This cooking time can vary between 3 to 5 minutes, depending on the specific pasta being used.

Once the sauce has finished cooking, drain the cooked pasta and transfer it to serving plates. Spoon the prepared sauce over the pasta, allowing each plate to be customized to individual tastes.
