Preparing Okinawan Sweet Potatoes for Microwaving
Before you start microwaving, it’s essential to prepare your Okinawan sweet potatoes properly.
1. Selecting Quality Sweet Potatoes
When choosing Okinawan sweet potatoes, look for the following characteristics:
- Evenly colored purple skin, free of blemishes or soft spots
- Firmness, indicating freshness
2. Cleaning the Sweet Potatoes
Rinse the sweet potatoes under cool running water to remove any dirt or grit. Using a vegetable brush may help ensure they are thoroughly clean.
3. Puncturing the Skin

Microwaving Okinawan Sweet Potatoes: A Step-by-Step Guide
Now that you have your sweet potatoes ready, let’s walk through the process of cooking them in the microwave.
Step 1: Prepare the Microwave
Ensure your microwave is clean and in working condition. If using a microwave-safe dish, it should be large enough to hold the sweet potatoes without crowding.
Step 2: Place the Sweet Potatoes in a Dish
Arrange the washed and punctured Okinawan sweet potatoes in a microwave-safe dish. Use a dish that can hold them without stacking, as the heat needs to circulate evenly.
Step 3: Cover the Potatoes
Cover the dish with a microwave-safe lid or wrap it in microwave-safe plastic wrap, leaving a small vent for steam to escape. This will help them cook thoroughly without drying out.
Step 4: Set the Microwave
Cook the sweet potatoes in the microwave at full power. For medium-sized Okinawan sweet potatoes, set the timer for about 5 to 7 minutes. If they are larger, you may need to cook them for up to 10 minutes.
Step 5: Check for Doneness
After the timer goes off, carefully remove the dish (it will be hot!) and check the potatoes for doneness by inserting a fork. If it goes in smoothly and the flesh is tender, they are ready. If they need more time, continue microwaving in 1 to 2-minute intervals until cooked through.
Step 6: Let Them Cool
Once done, let the sweet potatoes rest for a few minutes. This allows the steam to finish cooking them and helps in easy peeling if desired.
Enjoying Your Okinawan Sweet Potatoes
