Molecular gastronomy is the study of physical and chemical transformations of edible materials. Chefs use various techniques like spherification, gelification, thickening, and emulsification to transform tastes and textures of food. Key equipment used includes an anti-griddle to freeze items, a smoking gun for cold smoking, a rotary vacuum evaporator for essence extraction, sous vide for precise temperature cooking, and a dehydrator. Notable chefs who have innovated include Ferran Adria with olive spheres and Grant Achatz with edible balloons. Farzi Cafe aims to bring Indian cuisine to the forefront using modern presentations and cooking techniques to create illusions with food.
