Instead of deep-frying in lots of oil, the sweet potatoes are first precooked in the microwave and then pan-roasted in a little oil for easy preparation. Tossing them in a sugar and corn syrup glaze with nutty sliced almonds and crushed peanuts makes for a delicious sweet treat.

- Crushed peanuts1/4 cup

Steps


1. Peel 2 small sweet potatoes and cut them into 1.5-2 cm thick slices.
Place them in a strainer, rinse under running water, and drain off excess water roughly.
2. I prepared a little sliced almonds and crushed peanuts (chopped). I also added a bit of toasted sesame seeds.
You can also add other nuts like walnuts, pine nuts, or sunflower seeds.


3. Place the sweet potatoes in a wide dish, cover with plastic wrap, and microwave for 4 minutes.
They are fully cooked if a toothpick inserts smoothly.
If you cut the sweet potatoes smaller, cook them for under 3 minutes, and if you don't have a microwave, you can steam them in a steamer.
If deep-frying in oil, fry twice until golden brown.
In an oven preheated to 200 °C, bake for 20-30 minutes, adjusting the time depending on the thickness of the sweet potatoes.
4. Wipe away any moisture that came out during the cooking process.


5. Heat 2 tbsp of oil in a heated pan, add the sweet potatoes, and roast over medium-high heat until golden brown.
Shake the pan to turn them over and ensure they brown evenly.
Roasting them once like this prevents the surface from turning mushy
and gives you a texture that rivals deep-fried sweet potatoes.
6. Let's make the syrup. Add all the syrup ingredients and place over medium heat;
once it starts bubbling vigorously around the edges, leave it untouched without stirring.


7. Once it starts boiling toward the center and turns a caramel color...
8. Add the sweet potatoes and nuts together and quickly toss to coat.
Toss quickly because the ingredients won't coat evenly once cooled.
Ppunwife's tips
- Once it starts bubbling vigorously around the edges, leave it untouched without stirring.
- Toss quickly because the ingredients won't coat evenly once cooled.
- If you prefer it sweeter, make a generous amount of syrup and toss well.
