Sosa began as a family food business in Catalonia in the late 1960s and gradually evolved into one of the most technically diverse ingredient houses serving modern pastry and gastronomy. Its range addresses specific functions — gelling, thickening, aerating, emulsifying, stabilizing, sweetening and altering texture — alongside fruits, nuts, colours and concentrated flavours. Sosa is an important brand for Gusta because it gives chefs a vocabulary for formulation: instead of asking only what an ingredient is, it becomes possible to ask what it needs to do and choose a product for that precise technical role.
