What you will need

This recipe uses 9 simple ingredients that you can find at any grocery store:

  • 3 cups fresh watermelon chunks seedless
  • 1 whole jalapeno seeded and sliced
  • 2 tbsp fresh lime juice
  • 1 tbsp agave syrup
  • 1.5 cups ice cubes
  • 0.25 tsp salt
  • 2 slices watermelon wedge for garnish
  • 0.5 tsp chili lime seasoning
  • 2 rings jalapeno slices for garnish

Step by step instructions

Step 1: Prep the jalapeno

Slice the jalapeno in half lengthwise and remove all seeds and white membrane using a spoon. Wear gloves if your skin is sensitive. Slice into small pieces.

Step 2: Blend the base

Add watermelon chunks, jalapeno pieces, lime juice, agave syrup, and salt to a blender. Blend on high for 30 seconds until completely smooth.

Step 3: Add ice and blend again

Add ice cubes to the blender and blend again on high speed until the mixture becomes a thick slush consistency. Do not over blend or it will become too liquid.

Step 4: Taste and adjust

Taste the slush and adjust heat by adding more jalapeno or sweetness by adding more agave. Blend briefly after any additions.

Step 5: Serve and garnish

Pour the slush into chilled glasses. Sprinkle chili lime seasoning on top and garnish with a watermelon wedge and a fresh jalapeno ring on the rim.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • jalapeno → serrano pepper for more intense heat
  • agave syrup → simple syrup or honey
  • fresh watermelon → frozen watermelon chunks for a thicker slush

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Leaving seeds in the jalapeno which can make the drink unpredictably and overwhelmingly spicy
  • Over blending the ice which turns the slush into a watery liquid instead of a frozen texture
  • Not chilling the glasses beforehand which causes the slush to melt too quickly
