Prep the lime: Zest the lime first, then cut it and squeeze out the juice.
You’ll need about 2 tablespoons of juice. Avoid the white pith when zesting; it can be bitter.
Mince the garlic: If using garlic, grate it on a microplane or smash it into a smooth paste. Smooth garlic blends better and prevents sharp, raw bites.
Combine the base: In a bowl, add the mayonnaise, lime zest, and lime juice.
Stir until smooth.
Add the heat: Stir in your chosen chilli element. Start with less than you think you need (about 1 teaspoon for sauce or flakes), then increase to taste.
Balance the flavors: Mix in the garlic, a pinch of salt, a crack of black pepper, and the honey or sugar if using. Taste and adjust: more lime for brightness, more chilli for heat, or a pinch more salt to bring it all together.
Adjust the texture: For a dipping consistency, keep it thick.
For drizzling over tacos or salads, whisk in 1–2 teaspoons of water or neutral oil until it loosens slightly.
Rest: Cover and refrigerate for at least 15–30 minutes. This helps the flavors meld and the chilli settle into the mayo.
Serve: Use as a dip for fries, prawns, sweet potato wedges, or roasted veggies. Spread it on burgers, wraps, and sandwiches.
Drizzle over fish tacos, grilled corn, or grain bowls.
