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 combined with melted butter mimics the fat content of heavy cream (around 36-40%), which is crucial for achieving the creamy texture in chili. The fat helps stabilize the mixture against curdling when exposed to the chili's acidity and heat.
To ensure success, thoroughly blend the butter into the half-and-half before adding it slowly to the chili while stirring. Avoid boiling immediately after adding to prevent separation.
This substitute maintains the richness and mouthfeel of heavy cream, resulting in a chili that is creamy and smooth, closely matching the original recipe.
