Salad (sweet potato salad) | Kukipapa cooking channel's recipe

Peel off the skin of the washed sweet potato sprouts with a peeler and make a striped pattern.
Cut off the ends and slice into rounds (or chunks) to a uniform size.
Soak in water for about 5 minutes to remove bitterness.
Slice the onions along the grain.
Cut the ham into the size you like.
Put the sweet potatoes in a heat-resistant container, cover with plastic wrap, and heat in the microwave (600W) for 6 minutes.

Add butter and oil to a frying pan and heat.
Fry the onions and ham over medium heat and sprinkle the onions with salt.
When cooked, transfer to a large bowl.

When the sweet potatoes from step 1 are cooked, remove the plastic wrap and heat in the microwave (600W) for 1 minute to evaporate the moisture.
Mix sweet potato with 2, add mustard and mayonnaise and mix lightly.
Finally, mix capers as you like and transfer to a plate to complete.
