Korean Roasted Seaweed and Sesame Dip
A vibrant Korean-inspired dip combining nutty toasted sesame, umami-rich roasted seaweed, and creamy sour cream with a gentle heat from gochujang. The seaweed is lightly toasted to intensify its flavor, then blended with toasted sesame seeds, sour cream, and seasonings for a dip that's savory, slightly spicy, and deeply satisfying. Serve with vegetable crudités, crackers, or Korean rice cakes.

Steps
Before you start
- Have a small dry skillet ready for toasting
- Measure all ingredients before you begin toasting
- If your sour cream is cold from the fridge, let it soften slightly at room temperature for easier blending
Toast sesame seeds
- Place the sesame seeds in a small 8-inch (20 cm) dry skillet over medium heat.
- Toast for 2–3 minutes, stirring frequently with a wooden spoon, until fragrant and just barely golden.
- Be attentive—sesame seeds brown quickly and can burn.
- When you smell a nutty, toasted aroma and the seeds have lightened in color, pour them into a bowl and set aside.
- Do not wash the skillet yet.

Ready when: Sesame seeds are fragrant and light golden
Tip: Toast only until fragrant—overtoasted sesame becomes bitter. If in doubt, remove from heat a few seconds early.
Toast seaweed pieces
- Return the same skillet to medium heat (no need to wash it).
- Add the seaweed pieces in a single layer.
- Toast for 1–1.5 minutes, stirring occasionally, until the seaweed becomes slightly crispy and its aroma deepens.
- The seaweed should feel more brittle and smell more intensely umami-rich.
- Transfer to a cutting board and set aside to cool slightly.

Ready when: Seaweed is crispy and deeply aromatic, darker at edges
Tip: Seaweed is delicate—high heat will scorch it. Keep the flame at medium and stir gently.
Blend base ingredients
- Transfer the cooled seaweed and toasted sesame seeds to a food processor or blender.
- Add the sour cream (180 ml / 0.75 cup), gochujang (1 tbsp / 18 g), toasted sesame oil (1 tbsp / 15 ml), minced garlic (1 clove / 3 g), and soy sauce (0.5 tbsp / 7.5 ml).
- Pulse until the mixture is mostly smooth with small flecks of seaweed visible—do not over-blend, or the texture will become too uniform and lose its character.
- A few sesame seeds should remain slightly visible.

Ready when: Mixture is mostly smooth with visible specks of seaweed and sesame
Tip: Pulse in short bursts rather than running the food processor continuously, so the dip remains textured.
Season and finish
- Transfer the dip to a serving bowl.
- Taste and add the rice vinegar (0.5 tsp / 2.5 ml, optional but recommended for brightness) and adjust the salt to your preference.
- Stir in the sliced scallions, reserving a small pinch for garnish.
- If the dip seems too thick, stir in 1 tbsp of sour cream at a time.
- The final texture should be creamy and spreadable, not runny.

Ready when: Dip is evenly seasoned and has a creamy, spoonable consistency
Tip: Taste before the scallions go in fully—gochujang can vary in saltiness and spice by brand.
Good to know
Tips
- Toasting the seaweed and sesame seeds separately ensures each achieves its ideal texture and flavor without burning the other. Sesame seeds brown faster, so always toast them first.
- Gochujang brands vary in saltiness and heat—start with the amount called for, taste, and adjust. You can always add more gochujang mixed into a spoonful of sour cream, but you cannot remove it.
- This dip pairs beautifully with cucumber slices, radish sticks, lettuce leaves, roasted vegetable chips, Korean rice cakes (tteok), or crispy wonton strips. It's also excellent as a spread for grilled fish or chicken.
- For a spicier version, add a pinch of gochugaru (Korean red chili flakes) at the end, or drizzle extra sesame oil and a sprinkle of toasted sesame seeds over the top just before serving.
Make ahead
Dip can be made up to 3 days ahead and stored in an airtight container in the refrigerator. Flavors meld and deepen overnight. Stir well and adjust seasoning before serving, as the dip may thicken slightly as it sits.
Storage & reheating
Room temperature: up to 2 hours before serving. Refrigerator: up to 3 days in a covered container. Freezer: not recommended, as the sour cream base separates upon thawing. To reheat or serve after chilling, let the dip sit at room temperature for 10 minutes and stir to loosen.
Substitutions
- sour cream → Greek yogurt (full-fat) or crème fraîche. Use equal amounts by volume. Greek yogurt will yield a tangier, slightly thinner dip; crème fraîche is richer and closer to the original texture.
- gochujang (Korean red chili paste) → sriracha or Korean red chili flakes (gochugaru). Use 1.5 tsp sriracha for milder heat, or 0.5 tsp gochugaru mixed into the sour cream first. Both will shift the flavor profile slightly—gochujang adds fermented depth that these cannot fully replicate.
- roasted seaweed sheets (nori), cut into small pieces → nori flakes or dried seaweed (wakame), crushed. Use the same weight. Pre-roasted nori is ideal, but unroasted nori should be lightly toasted in a dry pan first.
- toasted sesame oil → roasted peanut oil. Use the same amount. The flavor will be nuttier but less distinctly Korean; consider adding an extra 0.25 tsp soy sauce for depth.
