How to Make Purple Sweet Rice Cakes: A Simple Recipe

Purple sweet rice cakes, or *zi shu song gao*, are a delightful, steamed Chinese dessert loved for their vibrant color, soft texture, and subtle sweetness. Here’s an easy step-by-step guide to making them at home.

Ingredients:

- 200g purple sweet potato, steamed and mashed

- 150g glutinous rice flour

- 50g all-purpose flour

- 80g granulated sugar (adjust to taste)

- 150ml warm water or milk

- 1 tsp vegetable oil

Steps:

1. Prepare the batter: In a large bowl, mix mashed purple sweet potato, glutinous rice flour, all-purpose flour, and sugar until well combined. Gradually add warm water/milk and oil, stirring until a smooth, thick batter forms (no lumps).

2. Rest the batter: Let it sit for 20 minutes to allow the flours to absorb moisture, resulting in a softer cake.

3. Steam the cake: Pour the batter into a greased round or square cake pan. Steam over high heat for 30-35 minutes. To check doneness, insert a toothpick—it should come out clean.

4. Cool and serve: Let the cake cool completely before slicing. It can be enjoyed plain or dusted with powdered sugar.

Tips: For extra flavor, add chopped dried fruits or nuts to the batter. These cakes are best served fresh but stay fresh in an airtight container for 2 days. Enjoy this healthy, visually appealing treat!
