Gelatin Strength & Bloom Converter
Recipe calls for gold sheets and you have powder? Convert between powdered gelatin, envelopes and bronze, silver, gold or platinum sheets, or find how much gelatin sets your liquid soft, unmoldable or firm.
How to use it
- Choose convert, or find how much for my liquid.
- Enter the amount and kind from the recipe (or your liquid and how firm you want it).
- Bloom the gelatin in cold water and dissolve it in the warm liquid.
How it works
Gelatin strength is measured in bloom. The pastry rule is that grams × bloom stays constant, so 4 gold sheets (2 g at 200 bloom) equal about 7 g of 225-bloom powder: one envelope. Manufacturers size sheets so one sheet of any grade sets about the same amount of liquid.
For setting liquids, it uses gelatin as a percentage of the liquid's weight with 200-bloom gelatin: about 0.6% for a soft set, 1% to unmold, 1.5% for a firm slice and about 6% for gummies, plus 25% for acidic or alcoholic liquids.
Assumptions: these results are estimates
- Bloom values are typical for each sheet grade and for Knox powder (about 225); brands vary.
- Setting percentages are starting points; temperature and other ingredients change the set.
Tips
- Never boil gelatin; it weakens. Dissolve it in warm liquid.
- Fresh pineapple, kiwi, papaya and mango stop gelatin setting unless cooked first.
- Gelatin sets fully in the fridge in 4 to 6 hours, and keeps firming overnight.

Questions
How many gelatin sheets equal one envelope?
About 4 gold or silver sheets equal one ¼ oz (7 g) envelope of powdered gelatin.
How do I substitute powdered gelatin for sheets?
Use about 1.8 g of powder per gold sheet, or simply 1 envelope for every 4 sheets.
How much gelatin to set 2 cups of liquid?
About one envelope (7 g) for a set that unmolds; less for a soft, spoonable set.
What is gelatin bloom?
A measure of gelatin's strength. Higher bloom sets firmer, so you use less of it.
