PerfectaGel is Super Premium Leaf Gelatine made in Germany. It is unflavored and can be used in both sweet and savory dishes. Professional chefs prefer leaf/sheet gelatine because it makes a clearer product with purer flavor and is easier to use. You can just count sheets rather than weighing out powder and there is no chance of undissolved granules. You can successfully substitute sheet gelatine for powdered gelatin in any recipe by using a rule of thumb of 1 sheet per 1/2 cup of liquid. PerfectaGel is made of 100% Grade "A" Collagen from Pork. And it is not appropriate for vegan, kosher or halal dishes. This assortment is the perfect way to sample all 5 strengths of PerfectaGel.
