![]() Add ice cubes to one container to cool the water.Fill the other two containers with about two cups of water each.Place one container in the freezer for at least 30 minutes.Pour about two cups of vegetable oil into each of two tall containers.Food coloring (red, blue or green work well).Unflavored gelatin powder, two seven-gram packages.In the kitchen it is often used for its unique texture. If prepared with water, the resulting gel is transparent, colorless and flavorless. These long strings interlace when cooled, however, and create a three-dimensional structure that can trap a lot of liquid. When gelatin is prepared, its proteins unravel as a response to added heat. This large protein is partially broken down and further treated to form gelatin. Collagen makes skin, bones and tendons strong and somewhat elastic. Gelatin is made of the protein collagen, a large fibrous molecule abundant in many animals, including humans. One can also make gel-like spheres using more common ingredients: gelatin and oil. There you have it-little drops of liquid confined in a thin, solid membrane! The outside of these spheres solidifies as a result of a chemical reaction between the two additives. When drops of the treated liquid fall into the bath they form small spheres. The most common method uses two chemicals, such as sodium alginate and calcium chloride: One chemical is dissolved in the liquid and another in a water bath. Spherification of juices, changing a liquid into semisolid pearls, is one example. Part of this field studies the influence food preparation techniques have on texture and flavor. Molecular gastronomy-the science of culinary phenomena-brings scientific procedures, ingredients and instruments into the kitchen. ![]() ![]() Do you enjoy getting creative in the kitchen? If so, this activity is for you! Molecular cuisine-taking tools, ingredients and methods typically used in science and using them in cooking-might sound fancy and complicated, but some techniques are easy to replicate!
