What makes jalapenos spicy?

The spiciness in jalapeños, and other chili peppers, comes from a compound called capsaicin.

Here's how it works:

* Capsaicinoids: Capsaicin is part of a group of chemicals called capsaicinoids, which are found in the placenta (the white membrane) and seeds of chili peppers.

* Heat Units: The spiciness of a pepper is measured in Scoville Heat Units (SHUs). Jalapeños typically range from 2,500 to 8,000 SHUs.

* Tricking the Brain: Capsaicin activates pain receptors in the mouth called TRPV1. These receptors are normally triggered by heat, but capsaicin tricks them into signaling a burning sensation, which we perceive as "spice."

* Body's Response: The body reacts to the burning sensation by releasing endorphins, which can have a stimulating and even euphoric effect.

So, the more capsaicin a pepper contains, the hotter it will be! 🌶️
