My sister told me about the idea of stir frying choy sum with goji berries many years ago, when goji berries were still unfashionable.
Until then, we had only had goji berries either as a snack straight off the packet or as one of the ingredients of various medicinal or traditional soups.
I tried stir frying choy sum with goji berries a few times and liked it. The sweet and sour taste of goji berries complements the mildly bitter taste of choy sum very well. Some people may not like the soft and mushy texture of cooked goji berries. But, for me, the goji berries make the choy sum stir fry look quite pretty and they provide a nice contrast in taste and texture.
To stir fry choy sum with goji berries, rinse 1 tablespoon of dried goji berries and set aside. Chop 1 clove of garlic finely. Chop 1 bunch of choy sum into bite-size pieces. Heat 1 tablespoon of oil over medium heat in a pan. Add the garlic and stir fry until fragrant. Add the choy sum and a splash of hot water. Add salt to taste. Mix well. Cover the pan for 3-4 minutes. Add the goji berries and stir. Cover the pan for another 1 minute. Serve warm.
