- 4 cloves garlic (freshly peeled)

Step-by-Step Instructions
Mortar and Pestle Method
-
Pound the Base: Start by placing the garlic, chilies, and cilantro stems into your mortar. Using a pestle, pound them together until you achieve a smooth paste, releasing all those glorious aromas. This should take about 1-2 minutes.
Chef’s Tip: A bit of sea salt can help break down the ingredients quicker.
-
Incorporate Sweetness: Add the finely chopped palm sugar to the mix and pound until it dissolves completely, about another minute.
-
The Final Mix: Pour in the fish sauce and lime juice, then mix thoroughly using the pestle until well combined. Taste and adjust seasoning as necessary.
-
Storage: Transfer your sauce to a jar or container, seal it tightly, and store in the fridge. It should keep well for about a week!
Blender Method
-
Combine Ingredients: Place all ingredients – garlic, chilies, cilantro stems, palm sugar, fish sauce, and lime juice – into your blender.
-
Blend Away: Pulse on medium speed until well mixed, but ensure you don’t liquefy it completely; it should retain a bit of texture—about 30 seconds.
-
Taste Test: Just like with the mortar method, taste and adjust flavors as desired.
-
Store: Pour into a container and refrigerate for up to a week.
Common Mistakes to Avoid
- Over-blending: If using a blender, don’t turn it into a complete liquid; a bit of texture is desirable.
- Too Much Fish Sauce: Start with less, and always taste as you go!
