✓ Ingredients
🥣 Main Ingredients
- 70 g (2.5 oz) walnuts
- 30 ml (1 fl oz / 2 tbsp) water
- Enough water for blanching
🧂 Sauce & Seasonings
- 75 g (2.6 oz) sugar
- 10 g (0.35 oz) butter
(Measurement guide: 1 tbsp = 15 ml, 1 tsp = 5 ml, 1 Korean paper cup = 180 ml / 6.1 fl oz)
✓ How to Make Caramel Walnuts
- Blanch the walnuts: Add the walnuts to boiling water and blanch for about 1 minute to reduce their bitter and astringent taste. Drain well in a colander.
- Add the walnuts to the syrup: Pour 30 ml (1 fl oz / 2 tbsp) water and 75 g (2.6 oz) sugar into a skillet. Once the sugar is thoroughly moistened, add the blanched walnuts.
- Stir occasionally: As the sugar melts, gently stir from time to time so the syrup coats the walnuts evenly.
- Caramelize the sugar: When the syrup begins to deepen to a brown caramel color, gently swirl the skillet so the walnuts color evenly on all sides.
- Add the butter and coat: Turn off the heat or reduce it to low, then add 10 g (0.35 oz) butter. Stir quickly until the butter melts and coats the walnuts. The butter adds shine and helps keep the walnuts from sticking together.
- Spread out and cool: Line a wide tray or baking sheet with parchment paper. Spread the caramel walnuts out in a single layer without overlapping, then refrigerate for 5–10 minutes to cool and set.
- Separate and store: Once the coating is crisp and firm, separate the walnuts one by one and transfer them to an airtight container or glass jar.
✓ Key Tips for Success
- Once the sugar syrup begins turning brown, it can burn very quickly. As soon as the caramel color appears, reduce the heat and gently swirl the skillet to distribute the heat evenly. This helps create a sweet caramel coating without a burnt, bitter taste.
✓ Serving Tips
- Roughly chop the caramel walnuts and sprinkle them over burrata or a fresh vegetable salad for a sweet, nutty crunch.
- Mix them into stir-fried anchovies at the final stage for a sweet-and-savory Korean side dish.
- Pack the walnuts in a decorative glass jar and tie it with a ribbon for a simple homemade gift or thank-you treat.
✓ How to Choose Good Walnuts
- Shell and appearance: For in-shell walnuts, choose clean shells without holes or major damage. For shelled walnuts, look for intact kernels with a light golden-brown color and a slight natural sheen.
- Weight and movement: In-shell walnuts should feel relatively heavy for their size. When shaken, the kernel should not rattle loosely inside the shell.
- Aroma and dryness: Choose walnuts without a rancid or musty smell. They should have a clean, nutty aroma and feel dry rather than damp or soft.

✓ Frequently Asked Questions (FAQ)
Q1. Won’t blanching the walnuts make them soggy?
No. Blanching them briefly for about 1 minute helps remove some surface impurities and bitterness. After they are cooked in the syrup and chilled, the moisture evaporates and the coating sets into a crisp texture.
Q2. Should I keep stirring the sugar syrup with a spatula while it cooks?
Avoid stirring too aggressively before the sugar has fully melted, as this can encourage crystallization and make the syrup turn cloudy and grainy. Gently swirl the skillet or stir only lightly from time to time until the sugar melts.
Q3. Can I use other nuts instead of walnuts?
Yes. You can use almonds, pecans, cashews, or other nuts with the same method. For nuts with less bitterness, such as almonds, you can skip the blanching step and cook them directly in the syrup.
The crisp caramel coating and rich walnut flavor come together in a simple snack that is hard to stop eating. Enjoy these caramel walnuts on their own, or use them as a sweet, crunchy topping for salads, ice cream, or cheese dishes.
Because they require only a few ingredients and about 15 minutes of cooking time, they are easy to prepare whenever you want a quick homemade treat.
