Before diving into spicy foods, it's crucial to understand the Scoville Heat Unit (SHU) scale, which measures the spiciness of peppers and foods. Bell peppers register at zero SHUs, while jalapeños range from 2,500 to 8,000 SHUs. For beginners, starting with foods in the 1,000 to 5,000 SHU range provides a gentle introduction to heat.
Your current spice tolerance depends on several factors, including genetics, cultural background, and previous exposure to spicy foods. Some people naturally have more sensitive taste buds, while others can handle moderate heat from the start. Take an honest assessment of your current comfort level by trying a small amount of mild salsa or a single jalapeño slice.
