Step-by-Step to Making Wai San Soup
Step 1: Preparing the Ingredients
Before you start cooking, it’s important to prepare the ingredients. Here’s how to get them ready:
Wai San (Chinese Yam): If you are using fresh Wai San, peel the skin carefully. Cut it into slices or chunks, depending on your preference. If you’re using dried Wai San, soak it in warm water for 30 minutes before use to rehydrate it.
Chicken: If you’re using bone-in chicken, wash it thoroughly. Some people like to blanch the chicken first to remove any impurities. To do this, place the chicken in a pot of boiling water, cook for 2–3 minutes, and then drain the water.
Red Dates, Goji Berries, and Chinese Wolfberries: Rinse them briefly in cold water to remove any dirt or dust.
Ginger: Peel a small piece of ginger and slice it thinly to release the flavor.
Optional Additions: If you’re adding lotus seeds, dried longan, or ginseng, make sure to rinse them first.
Step 2: Cooking the Soup
Now that the ingredients are prepared, it’s time to start cooking. You can use either a pot or a slow cooker to make Wai San soup, depending on your preference and available time. Both methods yield excellent results.
Using a Pot:
Start with boiling water: Begin by adding 8-10 cups of water to a large pot. Bring the water to a boil over medium-high heat.
Add the chicken: Once the water is boiling, add the chicken (either whole pieces or chopped). Let it cook for about 5 minutes, then remove the chicken from the pot. Discard the water (this is the blanching process).
Add fresh water and the rest of the ingredients: Refill the pot with 8–10 cups of fresh water. Add the chicken back into the pot along with the Wai San, red dates, goji berries, wolfberries, ginger, and any other optional ingredients like lotus seeds or dried longan.
Simmer the soup: Bring the soup to a boil again, then lower the heat to a simmer. Cover the pot with a lid and let it cook for about 1.5 to 2 hours. If you’re using pork bones instead of chicken, you may need to simmer the soup for 2-3 hours to fully extract the flavors.
Season the soup: About 30 minutes before finishing, taste the soup and add salt to your liking. You can also add more goji berries or red dates if you prefer a sweeter taste.
Using a Slow Cooker:
Combine all ingredients: Place all the prepared ingredients, including the chicken, Wai San, red dates, goji berries, wolfberries, ginger, and any optional ingredients, into your slow cooker.
Add water: Pour in 8-10 cups of water, ensuring that all ingredients are submerged.
Set the slow cooker: Set the slow cooker on low and let it cook for 4-5 hours, or on high for about 2.5-3 hours. The slow cooking method extracts more flavor from the ingredients and gives the soup a richer taste.
Season to taste: Once the cooking time is complete, taste the soup and adjust the seasoning by adding salt, if necessary.
Step 3: Serving the Soup
Once the soup is ready, it’s time to serve! You can ladle the soup into bowls and enjoy it hot. This soup is usually served as a main dish, and it’s perfect for a family dinner or a cozy meal on a chilly day. You can garnish it with a few more goji berries or wolfberries for added color and flavor.
Step 4: Storing Leftovers
If you have leftovers, Wai San soup can be stored in the fridge for up to 3 days. Simply let the soup cool to room temperature before refrigerating it. Reheat it in a pot on the stove, and add a little water if it has thickened too much.
You can also freeze the soup for up to a month. When ready to eat, thaw it in the fridge overnight, and then reheat on the stove.
