What Is Black Sesame Seed Paste?

Black sesame seed paste is made by grinding toasted black sesame seeds into a thick, smooth paste. It’s similar in concept to peanut butter or tahini, but the flavor is much deeper, nuttier, and slightly smoky.

Unlike the common white sesame paste (tahini), which is popular in Mediterranean cuisine, black sesame paste is more commonly found in East Asian cooking. In Japan, it’s known as kurogoma paste; in China, hei zhi ma jiang; and in Korea, heukimja. It’s used in both sweet and savory dishes, ranging from fillings in buns and mochi to dressings for noodles and salads.

The beauty of making black sesame paste at home is that you control the sweetness, consistency, and flavor intensity something store-bought versions can’t always deliver. Plus, it’s often more economical and fresher when prepared in your own kitchen.

Ingredients Needed

Making black sesame paste doesn’t require an extensive ingredient list. The magic lies in the simplicity:

Essential Ingredients

• Black sesame seeds – The star of the recipe. Opt for raw, unhulled seeds for maximum flavor and nutrition. Hulled seeds are less bitter but slightly milder.
• Neutral oil – To help transform the ground seeds into a smooth paste. Options include:
  • Grapeseed oil
  • Canola oil
  • Light sesame oil (for a more pronounced flavor)
• Sweetener (optional) – For sweet versions used in desserts. Options include:
  • Honey
  • Maple syrup
  • Brown sugar or white sugar
  • Agave nectar
• Salt (optional) – A pinch balances bitterness and enhances flavor.

Ingredient Notes

• If you plan to use the paste in savory recipes like dressings or marinades, skip the sweetener.
• If you’re using it primarily for desserts, adding sugar or honey will give it that indulgent quality.

Equipment Required

While the ingredient list is minimal, having the right equipment ensures you achieve a smooth, creamy paste:

• Skillet or pan – For toasting the sesame seeds evenly.
• High-powered blender, food processor, or spice grinder – Necessary to grind the seeds into a paste. A spice grinder will make a fine powder quickly, while a blender or processor will help incorporate oil.
• Airtight glass jar or container – For storing the paste in the refrigerator or freezer.

Optional: a fine mesh sieve if you want to sift out any coarse bits after grinding (more common in Japanese-style smooth pastes).

Preparing the Sesame Seeds

The preparation of the seeds sets the foundation for flavor.

1. Rinse (optional) – Some cooks like to rinse the sesame seeds quickly to remove any dust. Drain thoroughly and dry before toasting.
2. Toast the seeds – Heat a dry skillet over medium-low heat. Add the sesame seeds and stir continuously. They should release a nutty, fragrant aroma. This step is crucial because toasting enhances flavor and removes bitterness.
3. Avoid burning – Sesame seeds can burn quickly, and burnt seeds will make the paste bitter. Keep stirring and remove from heat once they’re fragrant and slightly popping.
4. Cool completely – Allow the toasted seeds to cool before grinding. Grinding warm seeds can cause clumping and uneven texture.

Grinding the Seeds

The transformation from toasted seeds to silky paste happens in two stages:

1. Grind into powder – Place cooled sesame seeds into your grinder or food processor. Pulse until they form a fine, sandy powder.
2. Continue blending – The seeds will release natural oils as you process them. Depending on your machine, this may take several minutes.
3. Add oil – Once the mixture starts clumping, slowly drizzle in neutral oil until the paste reaches your desired consistency.

Adjusting Consistency and Flavor

Black sesame paste can be made plain, sweet, or savory, depending on your intended use.

• Plain – Just sesame seeds and oil. Perfect for sauces, dressings, or as an ingredient in baked goods.
• Sweetened – Add sugar, honey, or syrup while blending. Ideal for desserts, spreads, or drinks.
• Savory – Keep plain, but add a pinch of salt to enhance the umami flavor.

Texture options:

• Thick paste – Great as a filling or spread.
• Smooth and runny – Works well as a sauce base or drizzle.

Storage and Shelf Life

Homemade sesame paste doesn’t contain preservatives, so storage is important:

• Airtight container – Store in a glass jar with a tight lid.
• Refrigerator – Keeps fresh for 1–2 weeks. Stir before use, as natural separation may occur.
• Freezer – For long-term storage, freeze in small portions (ice cube trays work well). Defrost as needed.

Ways to Use Black Sesame Paste

One of the most exciting aspects of making black sesame paste is discovering its versatility. Here are some delicious ways to incorporate it:

Sweet Uses
