Before diving into fiery dishes, it's essential to understand how spice tolerance works. Your ability to handle heat is largely determined by your exposure to capsaicin, the compound that makes peppers hot. The more you consume spicy foods, the more your taste buds adapt, allowing you to enjoy higher heat levels over time.
Start by familiarizing yourself with the Scoville Heat Unit scale, which measures pepper intensity. Bell peppers register zero Scoville units, while jalapeños range from 2,500 to 8,000 units. Serrano peppers jump to 10,000-25,000 units, and habaneros can reach 100,000-350,000 units. Understanding these measurements helps you make informed choices about what to try next.
