Whole Milk and Unsalted Butter (Best Option)
For every 1/4 cup heavy cream, use 3 tbsp whole milk + 1 tbsp melted unsalted butterHeavy cream is about 36-40% fat, which contributes to the tenderness and moisture of focaccia dough. Combining whole milk (3.5% fat) with melted unsalted butter increases the overall fat content to approximate heavy cream’s richness, supporting gluten development and crumb softness.
To ensure even incorporation, melt the butter and mix thoroughly with milk before adding to the dough. Avoid overheating the butter to prevent altering yeast activity. This substitute integrates smoothly without affecting dough hydration significantly.
Compared to pure heavy cream, this substitute yields a focaccia with a slightly lighter crumb but retains the characteristic moistness and flavor depth, making it an excellent practical alternative.
