There are those who love chilli and spicy pepper madly and those who, at the mere thought, start to sweat. In everyday life we already feel courageous when we face a spicy oil on pizza, a teaspoon of Calabrian ‘nduja, a classic garlic, oil and chilli pasta or jalapeños on nachos. However, those levels of spiciness are a walk in the park when compared to the real “monsters” of the world.
To measure the degree of spiciness – given by the capsaicin molecule – of a food, the Scoville scalea system created in 1912 by the American pharmacist Wilbur Scoville which is based on the quantification of the capsaicinoids contained in the food. The ranking starts from level zero, occupied by the classic sweet pepper, and then increases in intensity with the Italian chili pepper (100-500 SHU), the jalapeñowhich varies between 2,000 and 50,000 units, andHabanerowhich stands at around 250,000 units. At the top of the ranking, however, there are extreme varieties, obtained specifically through crosses between different chili peppers, such as Pepperthe spiciest of all with values that can exceed 2.6 million units and the Carolina Reaper.
