Basic spherification is created by submerging a liquid mixed with Sodium Alginate into a bath of Calcium Chloride. This technique allows you to transform liquid elements that can be manipulated into spheres. The spheres are composed of a gel-like membrane on the outside while keeping the liquid center. Sodium Citrate is used to correct the pH when using highly acidic liquid substances like citrus fruit. The Artistre line of products allows you to create spheres in any size you can image from small "caviar" to "ravioli" spheres.
