How to Make Hot Sauce From Scratch
Making hot sauce at home is simpler than most people expect. The core formula is ancient: peppers + acid + salt. Everything beyond that is flavor development. This guide walks you through a foundational sauce that produces a genuine, shelf-stable hot sauce on your first attempt.
Choose your peppers
Start with something accessible — jalapeños, serranos, or fresno chilis are ideal for a first batch. You want 8–12 oz of fresh peppers. Remove stems but keep seeds and membrane for now; you can adjust heat down in subsequent batches by seeding before cooking.
Simmer with aromatics
Combine peppers, 4 cloves garlic, half a white onion (rough-chopped), and 1 cup water in a saucepan. Simmer on medium-low for 20 minutes until peppers are completely soft and the liquid has reduced slightly. The simmering mellows raw pepper bitterness and melds the aromatics.
Blend
Transfer to a blender with ½ cup white vinegar and 1½ tsp kosher salt. Blend on high for 90 seconds. The vinegar is both flavor and preservation — it drops the pH below 4.0, which is the threshold for shelf stability. Taste and adjust: more vinegar for brightness, more salt for depth.
Strain (optional)
For a smooth sauce, strain through a fine mesh strainer, pressing solids with a rubber spatula. For a thicker, chunkier sauce, skip this step. Neither is more correct — it depends on how you want to use the sauce.
Rest and bottle
Let the sauce cool to room temperature, then refrigerate for at least 24 hours before using. The flavors integrate and mellow significantly overnight. Bottle in clean glass jars or swing-top bottles. Refrigerated, it keeps for 2–3 months.
Pro tips
- —Roast half your peppers in the oven at 450°F before simmering — it adds smokiness without needing a smoker
- —Apple cider vinegar adds a subtle sweetness that white vinegar lacks; try a 50/50 blend
- —A pH meter (under $15) tells you definitively whether your sauce is shelf-stable
- —Add a small roasted carrot for sweetness and body without sugar
