Preparation
Step 01
Place the jalapeños and serrano peppers onto a cutting board and use a sharp knife to remove the stems. Chop roughly and place into a blender, keeping the seeds and membranes, but discarding the stems.
Step 02
Add the garlic, sugar, salt and water to the blender and process until smooth.
Step 03
Pour the mixture into a large glass container and cover with plastic wrap.
Step 04
Leave it in a cool, dark place for 3 to 5 days to ferment, stirring and scraping down the sides each day, then replacing the plastic wrap.
Step 05
When bubbles start to appear, pour the mixture back into the blender along with the vinegar and blend together until smooth.
Step 06
Pour the mixture through a fine mesh strainer into a small saucepan, using the back of a spoon to push as much of the pulp through the gaps as possible. Discard the seeds and skin left behind in the strainer.
Step 07
Place the saucepan onto the stove and bring to the boil, stirring frequently, for around 5 to 10 minutes, or until the sauce has reduced down to your desired consistency (remember it will thicken further as it cools). Skim off any foam that forms on the surface.
Step 08
Remove from the heat and leave the sauce to cool to room temperature, then decant it into a jar and store in the fridge.
