Carrot gives body and sweetness so the heat reads as sauce, not a dare.
Ingredients
10 green habaneros, stemmed
2 carrots, peeled, in 2-inch chunks
1 small yellow onion, quartered
4 garlic cloves, peeled
½ cup lime juice (4–5 limes)
½ cup apple cider vinegar
¾ cup water
2 tsp fine sea salt
Juice of 1 more lime, at the end
Optional, and worth it: the red fresno, 3 jalapeños, the pale green wax pepper and the thin green chilli. Flavour, almost no extra heat.
Air fryer — roast first
Roasting is what lets you use less acid. Charred skins and sweet onion do the balancing that vinegar would otherwise have to do.
Gloves on. Habanero oil does not wash off with soap.
Toss carrots, onion and garlic with 1 tbsp oil. Air fryer, 390°F, 12 min, shaking once.
Add the habaneros and any optional peppers, whole. 390°F, 6 more min, until the skins blister and blacken in patches.
Garlic browns fastest — pull it early if it is colouring hard.
No air fryer: one sheet pan, 425°F, 25 min, peppers added for the last 8.
Sauce
Everything roasted into a saucepan with the lime juice, vinegar, water and salt.
Simmer lid on, 10 min. Keep it covered and run the hood — uncovered habaneros clear a room.
Off the heat, cool 10 min.
Blend 2 full minutes. Under-blending is what makes a hot sauce gritty.
Add the last lime, blend 10 seconds.
Salt to taste. It wants more than you expect.
Thin with water a tablespoon at a time. Strain for glass-smooth, or leave it.
Bottle, fridge.
On the acid
Acid is not a flavour choice, it is what keeps the sauce. Below pH 4.6 nothing dangerous grows. It does not have to be vinegar — lime is just as acidic and tastes bright instead of sharp.
As written: half lime, half cider vinegar. Keeps 4 months.
No vinegar at all: 1 cup lime juice (8–10 limes) instead of both. Better flavour, keeps 1 month. Freeze half in an ice cube tray on day one.
Skipping acid is not an option. If you want that, treat it as fresh — one week, then freeze.
Notes
Better after three days; the raw garlic edge settles.
Freeze the other 10 habaneros whole. The next batch can be hotter.
Not for the baby. Wash the blender jar before anything of hers goes in it.
