How to Predict a Jalapeño’s Spice Before You Taste It

Jalapeños get their heat from capsaicin, the compound responsible for the spiciness of all chillies. However, the amount of capsaicin in each pepper can vary greatly due to factors like growing conditions, ripeness, and genetics.

Peppers grown in hot, dry climates often have higher capsaicin levels. Stress during growth, such as inconsistent watering, can also result in spicier peppers. Ripeness plays a role too; green jalapeños tend to be milder, while red, fully ripened ones pack more heat.

Signs of a Spicy Jalapeño

Look for Striations (Corking)

White lines or small cracks on the pepper’s skin, known as corking, often indicate a spicier jalapeño. These marks show that the pepper experienced stress during growth, leading to higher capsaicin levels. Smooth-skinned jalapeños are generally milder.

Check the Color

Darker green peppers are usually spicier than lighter ones. If the jalapeño has started turning red, it’s likely to be hotter as the capsaicin levels increase with ripeness.

Size Matters

Smaller jalapeños often have a more concentrated heat compared to larger ones. If you’re looking for a milder option, choose the bigger peppers.

Smell It

Cut the pepper and take a sniff. A stronger, more pungent aroma can signal a spicier pepper, while a mild smell suggests less heat.

Taste the Tip

If you’re unsure, cut a small piece from the tip of the pepper and taste it. The tip is milder than the rest, so it gives you a safe preview of the heat without overwhelming your palate.

How to Handle Spicy Jalapeños

If you accidentally pick a pepper that’s too hot, don’t worry. Here are some ways to manage the spice:

• Remove the Seeds and Membrane: Most of the heat is concentrated here, so removing these parts can significantly reduce spiciness.
• Pair with Dairy: Sour cream, yoghurt, or milk can help neutralize the heat. Add these to your dish if needed.
• Use Sweet Ingredients: Adding a touch of sugar or honey can balance the spice in recipes.
