Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted unsalted butter per 1 cup heavy creamHalf-and-half combined with melted butter increases the fat content to approximate heavy cream's 36-40% fat, which is crucial for preventing curdling and ensuring a smooth, creamy texture in stews. The fat coats proteins and stabilizes emulsions during slow cooking.
To use, melt the butter gently and whisk it into the half-and-half thoroughly before adding to the stew. Add towards the end of cooking on low heat to prevent separation.
This substitute yields a stew that is rich and creamy, very close to the original heavy cream version, with minimal difference in mouthfeel or flavor.
