- Why did the sugar harden?
- Adding cold liquid to hot caramel causes thermal shock. Just keep heating gently until it remelts.
- How dark should it be?
- Dark amber. Too light = sweet; Black/smoking = burnt and bitter.
Vietnamese Caramel Fish Sauce (Nuoc Mau)
'Nuoc Mau' or caramel cooking sauce is a secret weapon of Vietnamese kitchens. It gives famous 'Kho' dishes (like clay pot pork or fish) their beautiful mahogany color and bittersweet depth. This isn't dessert caramel: sugar is taken almost to the smoking point to create savory, roasted notes that pair perfectly with salty fish sauce.

Instructions
1
✓
Have everything ready ('mise en place'); caramel waits for no one. Mince garlic and ginger.
Tip: You won't have time to chop once the sugar starts browning.
2
✓
Spread sugar in a skillet over medium heat. Don't stir, just swirl the pan until sugar melts and turns dark amber.
Tip: Stirring can cause crystallization.
3
✓
When deep brown and fragrant (not burnt smelling!), remove from heat and carefully pour in 1/4 cup water. Stand back—it will steam violently!
Tip: This stops the cooking process.
4
✓
Return to heat, stir in sesame oil, garlic, and ginger. Cook for 1 minute.
Tip: Blooms the aromatics in the oil.
5
✓
Add stock, fish sauce, and chili. Simmer 5-8 minutes until slightly thickened and glossy.
Tip: The salty fish sauce and bittersweet caramel fuse here.
