Cook the veggies. Add carrots, peppers, garlic, onion, and water to a saucepan. Bring to a boil, then simmer until everything is soft—about 15 minutes.
Let it cool slightly. Don’t blend lava. Give it a few minutes unless you enjoy kitchen chaos.
Blend until smooth. Transfer everything to a blender. Blend until silky and bright. Scrape down the sides if needed.
Add vinegar and seasoning. Pour in vinegar, salt, optional sugar, and oil. Blend again briefly.
Adjust the texture. Too thick? Add a splash of water. Too thin? Simmer it a bit longer.
Taste and tweak. This is your moment. Add more salt, vinegar, or heat if needed.
Cool and store. Let it cool completely, then store in a clean jar or bottle.
