Mammoth Jalapeño Heat Level Explained

Standard green jalapeños: ~2,500 Scoville units (mild). Red = hotter. Heat lives in placental membrane holding seeds — not flesh.

"Mammoth" refers to size, not heat. Larger peppers may have more total capsaicin but similar concentration. For heat, let ripen red; for mild, pick green.
