โญ Whole Milk and Butter Blend (Best Nut-Free Option)
3/4 cup whole milk + 1/4 cup melted unsalted butter per 1 cup heavy creamHeavy cream is approximately 36-40% fat, which contributes to tenderness and moisture retention in sourdough bread. Combining whole milk (about 3.5% fat) with melted butter (about 80% fat) recreates this fat level, ensuring the dough remains hydrated and enriched.
For best results, melt the butter and mix it thoroughly with cold whole milk before adding to the dough to ensure even fat distribution. Avoid overheating the butter to prevent cooking the milk proteins.
Compared to pure heavy cream, this substitute maintains similar softness and crumb texture in the final loaf, with only a minimal difference in richness that is generally undetectable.
