Inventive delights for an elegant teatime

Matcha sweet-potato cakes

This confection strikes a wonderful balance between the flavor of sweet potatoes and the bittersweetness of matcha. The sweeter the potato variety used, the better the result will taste. Making extra effort to press the cooked tuber through a fine-mesh sieve will ensure a velvety texture.

(Makes 10, in molds 5.5 cm diameter by 2 cm high)

  • About 340 g sweet potato (enough to yield 250 g strained sweet potato)
  • 4½ Tbsp sugar
  • 60 ml milk
  • 60 ml heavy cream
  • 2½ Tbsp unsalted butter
  • Pinch of salt
  • 1½ Tbsp matcha powder
  • Yolk of 1 egg, plus extra for glazing

1 Preheat oven to 180°C (355°F). Wash sweet potatoes, wrap individually in foil, and bake for 30 minutes.

2 Test potatoes for doneness with a toothpick. When cooked through, peel them while still hot and strain flesh through a fine-mesh sieve, using a wooden spatula. The finer the mesh, the smoother the texture will be. Measure out 250 g sieved sweet potatoes and place in a bowl. Leave oven at the same temperature, as it will be used to bake the cakes.


3 Place sugar, milk, cream, butter, salt, and strained sweet potatoes in a pan and warm over medium heat, mixing well with a rubber spatula until butter has melted.

4 Once mixture has thickened, remove from heat. Add matcha powder and combine thoroughly. Add 1 egg yolk and mix well.

5 Place molds on a baking pan. Fit a pastry bag with a star-shaped tip, and transfer sweet potato mixture to bag. Squeeze into molds with a swirling motion.

6 Use a pastry brush to apply egg yolk for glazing. Bake 15 to 25 minutes.

7 Remove from oven when glaze has turned golden brown. Let cool before serving.
