Out of self-rising flour

Self-rising flour from all-purpose: two Extension ratios compared

Self-rising flour is all-purpose flour with baking powder and salt already mixed in. The two charts we use print different recipes for it, so both are shown and neither is picked.

Mississippi State takes a little flour out of the cup and adds more baking powder and salt. Colorado State keeps a full cup of flour and uses less of both.

All-purpose flour + baking powder + salt

The charts below do not print the same thing for 1 cup of self-rising flour. We show each one as printed instead of averaging them.

Grams are volume-to-weight estimates from USDA FoodData Central (SR Legacy): Wheat flour, white, all-purpose, enriched, bleached — 1 cup = 125 g; Leavening agents, baking powder, double-acting, sodium aluminum sulfate — 1 tsp = 4.6 g; Salt, table — 1 tsp = 6 g. Blank means the chart does not say which kind to use, or the unit is not a volume.

Before you swap

  • The gram weights under each card are estimates worked out from USDA data; they are there to make the two versions easy to compare.
