The purpose for blooming gelatin is to ensure a smooth texture in whatever you are preparing. If you do not bloom the gelatin before adding it to a recipe, you may have unwanted lumps of gelatin in the product. Add the gelatin to a cool liquid to dissolve and stir. Do not try to dissolve the gelatin in a hot liquid or otherwise you will have lumps. The blooming process takes about 3 to 5 minutes. After your gelatin has bloomed, you can now add it to your heated liquid so that it dissolves easily and completely.
