Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted butter per 1 cup heavy creamHalf-and-half typically contains 10-12% fat, much lower than heavy cream’s 36-40%. Adding melted butter increases the fat content, approximating heavy cream’s richness and emulsifying properties, which are crucial for creamy pasta sauces.
To ensure smooth incorporation, melt the butter and mix it thoroughly with half-and-half before adding to the sauce. Heat gently to prevent separation.
The final sauce will be nearly indistinguishable from one made with heavy cream, retaining a rich, velvety texture and stable emulsion, ideal for pasta applications.
