Hi Elizabeth, I think the flavor of the black rice will be great, but it requires different cooking method and water ratio. Does the video you watch steamed both together? You should follow the video and its instructions if you plan to use black rice.
My recipe only uses glutinous rice. Once you soak the rice, it doesn’t need extra water when you steam them. Black rice might require additional water even after pre-soaked.

In and Out is one of my favorite restaurants in Beijing! And this pineapple recipe was created after I ordered one there. My college loved the dish and asked me to recreate the recipe 🙂

Hi Celine, if you scroll down the recipe, you can find the section “To cook with pre-cut pineapple”. You can use the instructions there to cook the rice with a normal bowl instead of in the pineapple. Happy cooking!
