Recipe: Chawanmushi (Japanese Egg Custard)

For a yummy appetiser, try Bosch Partner Chef John See’s recipe for Chawanmushi, which contains eggs with betaine and choline and shiitake mushrooms – which have potent phytonutrients that help decrease low-density lipoprotein (can clog arteries and make heart attacks and strokes more likely) and very low-density lipoprotein (associated with the development of plaque deposits on artery walls, which narrow the passage and restrict blood flow) – maintaining good cardiovascular health for you and your family.

Chef’s tip: Strain the mixture through a fine sieve to ensure smooth consistency of the Chawanmushi.

4. Add the eggs into the mixture and mix well.

5. Place chicken and mushroom into cups or bowls that are suitable for steaming.

6. Distribute egg custard mixture equally into the cups or bowls.

7. Steam in a combi-steam oven or over a steamer for about eight minutes.

8. To see if cooked, insert a toothpick into the middle of the cup or bowl. If the toothpick comes out clean, the Chawanmushi is cooked.
