⭐ Sour Cream (Best Nut-Free Option)
1:1 by volumeSour cream contains similar fat content and acidity as Greek yogurt, which helps maintain the balance of flavors and creaminess in pasta dishes. Its lactic acid content prevents the sauce from becoming overly rich or flat.
When using sour cream, add it towards the end of cooking and avoid boiling to prevent curdling. Stir gently and heat on low to medium heat for best results.
The final pasta sauce will have a comparable tang and creaminess, with a slightly richer mouthfeel due to sour cream's higher fat content, but the difference is subtle and generally favorable.
