Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted unsalted butter per 1 cup heavy creamHeavy cream is approximately 36-40% fat, which contributes to the tenderness and flakiness of pie crust by coating flour proteins and limiting gluten development. Half-and-half alone (10-18% fat) is too low in fat, but when combined with melted butter (100% fat), the mixture approximates heavy cream’s fat content and moisture balance.
To ensure success, melt the butter and mix thoroughly with half-and-half before incorporating into the dough. Keep the mixture cold to prevent premature gluten development and maintain dough consistency.
Compared to using pure heavy cream, this substitute yields a very similar texture and flavor in the crust, with negligible differences in flakiness or tenderness.
