Popular questions
What does cream of tartar do?
Cream of tartar (potassium bitartrate) is a mild acid that stabilizes egg whites, helps prevent sugar crystallization, and activates baking soda for leavening.
What is cream of tartar used for?
It’s used to stabilize meringues and whipped egg whites, keep syrups and candies smooth, and provide lift in baked goods when paired with baking soda (often adding a slight tang).
Does cream of tartar go bad?
It doesn’t spoil and keeps indefinitely if stored airtight and dry, though it may clump; to check potency, mix a pinch with baking soda and hot water—vigorous fizzing means it’s still good.
What does cream of tartar do in cookies?
It provides the acid to react with baking soda for rise (as in snickerdoodles), contributing to a soft, chewy texture, subtle tang, and often a crackly surface.
How to make cream of tartar?
You generally can’t make it at home—it’s purified potassium bitartrate crystallized from wine production. For recipes, use 1 tsp lemon juice or vinegar per 1/2 tsp, or replace cream of tartar plus baking soda with about 1.5 tsp baking powder.
E337 sodium potassium tartrate is in what foods?
It’s used as a sequestrant and stabilizer in some beverages (e.g., soft drinks and juices), jams/jellies, sugar syrups and confectionery, and occasionally in processed fruits/vegetables or baking mixes; look for E337 on ingredient lists.
How to grow potassium sodium tartrate crystal?
Dissolve the salt in hot water to make a saturated solution, then let it cool or evaporate slowly to form crystals; larger crystals grow best from a clean seed crystal and in low humidity because Rochelle salt is deliquescent.
How to prepare potassium sodium tartrate?
It is produced by neutralizing tartaric acid with sodium and potassium bases (e.g., carbonates) and crystallizing the tetrahydrate (Rochelle salt). For food use, obtain food‑grade E337 rather than attempting home preparation.
How to prepare potassium sodium tartrate solution from sodium and potasium tartarate?
Simply dissolve sodium tartrate and potassium tartrate together in water to the desired concentration; in solution this is effectively potassium sodium tartrate, while isolating the true double salt requires crystallization from an equimolar mix.
How to prepare potassium sodium tartrate solution from sodium and potassium tartrate?
Dissolve appropriate amounts of sodium tartrate and potassium tartrate in water to reach your target strength; the mixed ions give a solution equivalent to potassium sodium tartrate, though the double salt forms only on crystallization.
