Agar agar is a carbohydrate that comes from the cell walls of seaweed. The seaweed is freeze-dried and dehydrated, then processed into powder, flakes, threads or bars. An effective gelatin substitute, this protein-rich product allows vegans to enjoy gelatin dishes. One bar is equivalent to 2 tsp. of gelatin. Getting the correct consistency for agar agar recipes can be tricky at first. However, it is very easy to correct any mistakes. If your product turns out too thick, simply reheat the mixture and add a bit more water. If it's too thin, add a bit more agar agar.
Grind a bar of agar agar in your coffee grinder, blender or food processor.
Put 2 cups of water in a pot on the stove, over high heat. Add the agar agar and bring the mixture to a boil.
Reduce the heat and allow the mixture to simmer. Stir constantly until the agar agar is fully dissolved.
Add your other ingredients, following the recipe you have chosen.
Leave the mixture to sit for an hour at room temperature. Agar agar does not require refrigeration to set.
