⚠️ Watch-outs & how to enjoy it better
The capsaicin that provides its signature burn can cause gastrointestinal discomfort, heartburn, or irritation for those with sensitive stomachs or conditions like IBS. To mitigate this, pair it with cooling dairy (like sour cream or cheese) or starchy foods, remove the seeds and white membrane where most capsaicin resides, or opt for milder preparations like roasting or pickling.

FAQ
How hot is a jalapeño on the Scoville scale?
Jalapeños typically range from 2,500 to 8,000 Scoville Heat Units (SHU), placing them in the mild-to-medium heat category. The heat can vary significantly based on growing conditions and ripeness.
What's the difference between a fresh and pickled jalapeño?
Fresh jalapeños have a crisp, grassy flavor and straightforward heat. Pickled jalapeños (often called 'nacho slices') are softer, tangy from the vinegar brine, and have a slightly mellowed, more complex heat.
Can I reduce the heat of a jalapeño before cooking?
Yes. The majority of the heat (capsaicin) is concentrated in the white pith (membrane) and seeds. Removing these parts before slicing or dicing will significantly reduce the spiciness.
