I've seen many different but I don't want to use too much gelatin and make my mousse rubbery. Is my calculation right or do I need to use some other conversion factor to get amount of sheets of gelatin. 76 which means that 3/4 a teaspoon of powder is equal to a sheet and 1.5 teaspoons is equal to 2 sheets which I found many places throughout the internet. I then took this and divided it by 2.33 which i found to be the amount of grams of gelatin powder in a teaspon and got. I read that Knox powdered gelatin is 225 bloom so I took 400 (the bloom for a sheet according to my theory) and divided it by 225 and got 1.77 meaning 1.7 grams of powdered should equal one sheet. 2 Im not able to purchase agar-agar (yet), so is there a rule for replacing the quantity Ive seen a recipe with 0,5 spoon of agar-agar for 1 spoon of gelatin. ![]() If 2.5 grams x 160 bloom (silver sheet) = 400 and 2 grams x 200 bloom (gold sheet) = 400 meaning that they are the same strength if calculated by sheets. ![]() I did some math of how I thought bloom worked. If I understand bloom correctly (which I probably don't), her statement is more true than Iuzinni's. Slightly less common rule: 1-1/2 sheets of gelatin 1 tsp. However, note that 1 pack of gelatin usually 2.5 (and not 3.0) tsp. Most common rule: 1 pack of gelatin 7.1 gms (approximately) 1/4 oz (exactly) 4 sheets (about) 1 tbs granulated (about). ![]() In Johnny Iuzinni's book "Desserts Fourplay" he says that all gelatin sheets are equal by weight but this contradicts what Claire Clark says in Indulge where shes says they are equal by sheets but not by weight. indigolotos/Shutterstock Most American recipes will call for powdered gelatin, likely because it is much easier to find in supermarkets. When it comes to making the conversion, caveat lector, standard doesnt mean perfect. For example, if a recipe calls for 2.6 g of Knox gelatin, you could use 3.7 g of silver gelatin, which has a Bloom strength of 160 (2.6 × 225 160 3.7). I was trying to convert gelatin sheets to an amount of Knox gelatin grams or teaspoons. For gelatin A, you can find the equivalent weight of gelatin B (MB) with a Bloom strength of BB by using the formula MB MA × BA BB.
