Ingredients

Instructions

  1. Step 1: Preheat a grill pan or outdoor grill to medium-high heat (about 400°F). Place 2 serrano pepper halves directly on the grill and char for 2-3 minutes per side until blistered and slightly blackened. Remove and let cool.
  2. Step 2: In a shaker, muddle the grilled serrano pepper halves with 4 fresh cucumber slices until the mixture releases aromatic juices, about 45 seconds.
  3. Step 3: Add 2 oz mezcal, 1.5 oz fresh lime juice, 0.5 oz agave nectar, and 1 large egg white to the shaker without ice. Shake vigorously for 15 seconds to emulsify the egg white.
  4. Step 4: Add ice cubes to the shaker and shake again for 20 seconds until the mixture is chilled and frothy.
  5. Step 5: Double strain the cocktail into a chilled coupe glass to remove solids and create a smooth texture. Garnish with 1 cucumber wheel floated on top.

Frequently asked questions

How long does Grilled Serrano Pepper and Cucumber Mezcal Sour take to make?

Total time is about 20 minutes (15 min prep + 5 min cook). Most home bartenders find this fits a single afternoon; scale up the batch for parties or pitchers.

How do I store leftover Grilled Serrano Pepper and Cucumber Mezcal Sour?

Refrigerate any leftover grilled serrano pepper and cucumber mezcal sour in a sealed pitcher or jar for up to 3–4 days. Do not reheat — drinks are served chilled. If the recipe uses sparkling water or fresh herbs, hold those back and add fresh just before pouring so the drink stays bright and fizzy.

Can I substitute ingredients in Grilled Serrano Pepper and Cucumber Mezcal Sour?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Grilled Serrano Pepper and Cucumber Mezcal Sour for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
