A Japanese Tip for Boiling Sweet Potatoes: Achieve Soft, Naturally Sweet Potatoes in Just 5-6 Minutes
Depending on your preference, you can choose between soft or sticky sweet potatoes.
Soft Sweet Potatoes: Opt for medium-sized potatoes that are intact and feel heavy for their size. When cutting off the ends, look for a light orange color and white sap.
Sticky Sweet Potatoes (Mật): Choose potatoes with a purplish hue and streaks of蜜 (honey) on the skin. The drier the potato skin, the more蜜 it will produce when baked.
Once you’ve selected your potatoes, give them a good scrub to remove any dirt or sand from the skin.
Preparing the Sweet Potatoes
Using a knife, cut off both ends of the potatoes. Then, use a skewer or a fork to prick holes all over the potatoes, or gently score them with a knife. This step helps to release steam and ensure even cooking, preventing the potatoes from exploding.
Wrap each potato tightly in a layer of paper towel or clean newspaper to retain moisture and create soft, moist potatoes without drying them out. For even cooking, you can also wrap them in plastic wrap suitable for microwave ovens.
Microwaving the Sweet Potatoes
Place the wrapped potatoes on a ceramic plate and put them in the microwave.
Adjust the cooking time: Depending on the size of the potatoes and the power of your microwave, set the cooking time accordingly. Typically, a medium-sized potato takes about 5-6 minutes on the high setting. For larger potatoes, increase the time to 8-9 minutes.
Remove the potatoes from the microwave and let them cool down before handling and enjoying.
Alternatively, you can place the potatoes in a bowl of water and microwave them. This method also results in soft, tender potatoes.
The Final Product
The cooked sweet potatoes will be soft, evenly cooked, and naturally sweet. This method is favored by Japanese mothers for its convenience and ability to retain the potatoes’ natural sweetness.
Who Should Avoid Eating Sweet Potatoes
Despite their numerous health benefits, sweet potatoes may be harmful to certain individuals:
People with kidney disease: Those with kidney problems should refrain from consuming sweet potatoes due to their high fiber, potassium, and vitamin A content. Weak kidneys may struggle to eliminate excess potassium, potentially leading to serious complications such as heart rhythm disorders.
Individuals with digestive issues: If you experience frequent bloating or abdominal dist, limit your intake of sweet potatoes as they can increase stomach acid secretion, causing hot intestines, acid reflux, and further bloating.
