  • Spice grinder or blender Only necessary if you are making your own black sesame powder
  • Pot & heat proof spatula


  • 0.33 lb Unsweetened Black sesame paste (150g) Substitute: dry fry sesame seeds till fragrant (70% black sesame and 30% white sesame to give the dessert a richer flavor). Once cooled, blend the seeds into sesame powder. Pulse intermittently- if you run the blender for too long you may end up with sesame paste. Alternatively, you can also buy black sesame powder at some Asian supermarkets- give it a quick toast to make it more fragrant, before continuing with the rest of the recipe
  • 1-2 Cups Water, or to taste (depending on how thick you like your dessert)
  • 1 T brown sugar, or to taste Substitute: rock sugar, white granulated sugar or a neutral honey
  • ½-1½ T Glutinous rice flour Substitute: you can use glutinous rice grains. These will have to be soaked for a minimum of 4 hours (or overnight) then blended with the black sesame seeds. Alternatively, you can use regular rice flour or ground oats.
  • 1 teaspoon Sesame oil or neutral vegetable oil Optional: this is to improve the texture of the soup and make it more silky
  • A pinch of toasted white sesame seeds Optional garnish
  • A splash of coconut milk


  • Add the black sesame paste (or powder) to the pot with the water and bring to a boil. If using black sesame paste, you will have to keep stirring to dissolve the paste into the water.
  • Once boiling (this soup heats up FAST), turn the fire down so that the soup is simmering. Start by adding in ½T glutinous rice flour and 1T sugar, stirring continuously to prevent the soup from catching at the bottom of the pot. If you want a thicker soup, add some more glutinous rice flour. (I usually add 1T of glutinous rice flour- start with less as you don't want to end up with a stodgy lump instead of a soup! If it becomes too thick, just add more water to thin it down.)
  • After simmering to your desired consistency, taste to see if the soup is sweet and thick enough. If not, add a bit more sugar and flour. Simmer for about 10 minutes, stirring continuously.
  • Before switching off the fire, add a teaspoon of sesame oil and mix it into the black sesame soup.
  • Ladle into bowls and serve warm. You may want to garnish each bowl with toasted sesame seeds and a drizzle of coconut milk.


Note: If you enjoy desserts like salted caramel, you may want to add a touch of salt. Salt helps to accentuate the flavour of desserts in my opinion, (e.g. salted chocolate chip cookies) but not everyone is a fan.
