Explanation

Use 240 g per US cup as the reference when converting sour cream from cups to grams.

Recipe scaling stays tied to the US cup standard (236.588 mL) rather than to mixed cup charts. Sour Cream can vary slightly with thickness, air pockets, and how compactly it fills the cup, so the page keeps one explicit basis for consistent kitchen reference.

Method & Cup Basis

Method basis: cup-to-weight conversion anchored to the US customary cup (≈236.6 mL).
Applied formula: grams = cups × 240.
Consistency rule: snapshot, calculator, FAQ, and table use the same ingredient-specific basis.

1/4	60
