Steps
Before you start
- Have a dry skillet or frying pan ready
- Use a small food processor, spice grinder, or mortar and pestle
- Measure all ingredients before you start toasting
Toast the sesame seeds
- Place sesame seeds in a dry 8–10 inch skillet over medium heat.
- Stir constantly for 2–3 minutes until fragrant and light golden, being careful not to burn them.
- Sesame seeds brown quickly, so watch closely.
- Transfer to a small plate to cool for 1 minute.

Ready when: Seeds are fragrant and light golden, not dark brown
Tip: Keep the pan moving to prevent burning; sesame seeds go from perfect to scorched in seconds.
Prepare grinding equipment
- While the seeds cool, set up your spice grinder, small food processor, or mortar and pestle.
- Ensure the vessel is completely dry with no moisture or residue from previous use, as any dampness will clump the blend.

Ready when: Equipment is clean and dry
Tip: A dry tool is essential for a free-flowing spice blend; moisture causes caking.
Add cooled seeds to grinder
- Once the sesame seeds are cool enough to handle (about 1 minute), transfer them to your grinder, food processor, or mortar.
- Add the gochugaru, garlic powder, black pepper, and sea salt.

Ready when: All ingredients are in the grinding vessel
Tip: Add cooled seeds last to avoid them melting or clumping with other powdered ingredients.
Blend to coarse texture
- If using a spice grinder or food processor, pulse for 1–2 minutes until the mixture is mostly broken down but still slightly coarse, with some small seed pieces visible (not a fine powder).
- If using a mortar and pestle, grind gently for about 2 minutes until roughly combined.
- The blend should smell fragrant and look uneven, with visible sesame flecks.

Ready when: Blend is coarse and fragrant, with visible sesame seed pieces throughout
Tip: Do not over-process; you want texture and some whole seed pieces for authentic Korean flavor, not a powdery blend.
Transfer to jar and label
- Pour the blend into a small airtight glass jar, scraping the bottom and sides of the grinder to get all the flavorful bits.
- Seal the lid tightly and label the jar with the date and contents.

Ready when: Blend is fully transferred and jar is sealed
Tip: Glass jars preserve flavor better than plastic; keep away from direct sunlight and heat.
Use as a finishing seasoning
- Use this blend as a finishing seasoning for soups, rice bowls, roasted vegetables, eggs, or any dish needing Korean heat and nutty depth.
- Sprinkle on at the last moment before serving to preserve the toasted sesame aroma and heat impact.

Tip: Sprinkle sparingly over finished dishes rather than cooking with it; the toasted flavor fades with heat.
Good to know
Tips
- Toast your own sesame seeds rather than buying pre-toasted for fresher, more vibrant flavor—the difference is noticeable.
- Use this blend as a finishing seasoning rather than cooking with it; sprinkle it on at the last moment to preserve the toasted sesame aroma.
- Adjust the heat level by reducing gochugaru to 2 tablespoons for a milder blend, or increase to 4 tablespoons if you love intense spice.
- This blend is excellent sprinkled over soft-boiled or poached eggs, roasted sweet potato wedges, cucumber salad, or warming bowls of miso soup or kimchi jjigae.
Make ahead
This blend can be made up to 3 months ahead and stored in an airtight container at room temperature.
Storage & reheating
Room temperature in an airtight glass jar: up to 3 months. Keep away from direct sunlight and moisture. No freezer storage needed; the blend keeps fresh at room temperature.
Substitutions
- sesame seeds, white → Black sesame seeds. Use the same amount for a more dramatic look and slightly earthier flavor. Toast the same way to release oils.
- gochugaru (Korean red chili flakes) → Aleppo pepper or ground cayenne. Aleppo pepper (Turkish) is milder and fruitier; use 2 tablespoons plus 1 teaspoon. Cayenne is much hotter; use only 2 tablespoons.
- garlic powder → Onion powder or a combination of both. Use 1.5 teaspoons onion powder alone for a sweeter profile, or mix 0.75 teaspoon each for balance.
- black pepper, freshly ground → White pepper. White pepper is slightly hotter and cleaner in flavor; use the same amount.
