Pinchwell, the Ingredient-Swap Reference Desk

Field notes

Pinchwell organizes substitution advice as a searchable reference desk, with browsing by dietary category and dish type alongside ingredient lookup. The visible examples include a 2¼-to-1 evaporated-milk reduction, a 1:1 cornstarch-for-arrowroot swap, and a buttermilk method that rests milk with vinegar or lemon juice for five minutes. The site says its ratios draw on USDA FoodData Central, King Arthur Baking, FDA standards, and university extension material.
