Choosing the Right Caramelization Method
- Best method for beginners: The water-and-oil mix method. It is the easiest to master, offers the best control over heat, and minimizes the risk of burning or bitterness.
- Recommended sugar type: Crushed rock sugar. It yields a vibrant, glossy red-amber color and a milder, more aromatic flavor than white sugar, making it less prone to bitterness.
- Golden ratio: Sugar : Water : Oil = 5 : 1 : 0.5. The oil serves only to coat the pan and prevent sticking; do not use too much.
Key Heat Control Points
- Never use high heat. Use medium-low heat until the sugar fully melts, then switch to the lowest setting immediately once the color begins to change.
- Keep the flame height below the rim of the wok/pan to prevent localized overheating, which could cause the sugar at the edges to burn and turn bitter prematurely.
- Once the sugar has melted into a liquid, avoid vigorous or frequent stirring. Let it cook naturally to prevent bringing the superheated sugar from the bottom to the surface too soon.
Recognizing Key Stages (Crucial for Avoiding Bitterness)
- Color progression: White → Pale yellow → Sesame oil color → Amber-jujube red. Turn off the heat immediately when it reaches the amber-jujube red stage and fine, uniform bubbles appear.
- If the syrup turns dark brown or black, it has over-caramelized and will inevitably taste bitter; you must discard it and start over.
- After turning off the heat, let the residual heat cook the syrup for a few seconds. When the bubbles shift from large to dense and tiny, immediately pour in boiling water (double the volume of the sugar). Never add cold water, as the sudden temperature drop can cause the sugar to clump and burn locally.
