Toydarian yeast was a type of cooking ingredient.
Toydarian yeast was a powerful rasing agent and could be used in cakes, to make cake layers float above each other. However, if it was used incorrectly, it could become explosive.
The Farghul Asora sold toydarian yeast in her shop, in Hedrett on Cularin. Shortly before the wedding of Lavina Wren and Jarid DeBell, Asora sold an extra-rising form of toydarian yeast to a group of Devaronians and she gave it to them in a sealed container, because it was so reactive. They Devaronians were working for the assassin Melo Centris and they gave her the yeast, which she used in a poisonous cake that she was making, to kill DeBell at the wedding.
