About ounces Baking Powder (ounces)
Ounces of Baking Powder. Measured by US avoirdupois ounce (= 28.349523125 g exactly per NIST SP 811 — distinct from fluid ounce which is a volume unit). Mass-ounce measurement is preferred in US butcher/bakery/professional contexts where precision matters but the recipe uses imperial customary units. Common US baking ingredient packages list both ounces (mass) + grams: a stick of butter = 4 oz = 113 g; a 'pound' of flour = 16 oz = 454 g. CRITICAL: do NOT confuse with the troy ounce (~31.1 g — used only for precious metals) or the fluid ounce (volume unit = 29.57 mL). Baking powder is a chemical leavening agent composed of baking soda (sodium bicarbonate) + one or more acids + a moisture-absorbing starch (typically cornstarch). When mixed with liquid + heat, the acid reacts with the bicarbonate to release CO₂ gas, leavening batters and doughs. Density ~0.900 g/mL. 'Double-acting' baking powder (US grocery default since the 1950s — Calumet, Rumford, Argo, Clabber Girl, Bob's Red Mill) contains two acids: monocalcium phosphate (releases CO₂ immediately upon mixing) + sodium aluminum sulfate or sodium acid pyrophosphate (releases CO₂ when heated in the oven). 'Single-acting' baking powder releases all gas immediately on mixing — batter must be baked immediately. Aluminum-free baking powder (Rumford, Bob's Red Mill) uses monocalcium phosphate + sodium acid pyrophosphate, avoiding the metallic taste some perceive in aluminum-containing brands. Shelf life ~6-12 months once opened (test by dropping a teaspoon in 1/3 cup hot water — should fizz vigorously). Density: 0.900 g/mL (used to convert volume measurements to mass).
About teaspoons Baking Powder (teaspoons)
Teaspoons of Baking Powder. Measured by US teaspoon (= 5 mL = 1/3 US tablespoon = 1/48 US cup per FDA 21 CFR 101.9). The teaspoon is the standard US measure for small dry ingredients (salt, sugar, baking powder, spices) + small liquid amounts (vanilla extract, lemon juice). Common multiples: 1/4 tsp (1.25 mL), 1/2 tsp (2.5 mL), 1 tsp (5 mL). 'Heaping teaspoon' is informally ~50% more than level (can vary widely). Most US measuring-spoon sets include 1/4, 1/2, 1, and 1 tablespoon (= 3 tsp) increments.
