Baking powder is a chemical leavening agent consisting of sodium bicarbonate, an acid (typically cream of tartar or sodium pyrophosphate), and a starch filler. It provides no meaningful macronutrients but contributes significant sodium; a teaspoon (~4g) contains around 400–500mg sodium. It is used in very small quantities to aerate baked goods and should not be confused with plain flour or bicarbonate of soda.
Use the quantity specified in the recipe — too much baking powder produces a bitter, soapy taste and can cause baked goods to collapse. Check the expiry date; old baking powder loses its potency and results in flat bakes.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
