Wash the jalapenos thoroughly to remove dirt.

Cut off the stems and roughly chop the jalapenos.

In a medium saucepan, add the chopped jalapenos, garlic, vinegar, water, salt, and sugar.

Heat the mixture over medium-high heat until it reaches a boil.

Reduce the heat and let it simmer for 10 minutes.

Carefully transfer the hot mixture to a blender and blend until smooth.

Taste the hot sauce and adjust the heat as desired.

Pour into a glass bottle or jar and let it cool before sealing.
