My EE will add a small portion of pork (around 1/3 bowl) and fish to congee together with different kinds vegetable (e.g. carrot, chestnut, pumkin, sweet potato etc).
My EE will use Philips blender to blend the pork. While blending, she will add cold water. The pork becomes very creamy, just like milk shake. Then cook it for 10-15 mins, not 鞋.
