Mr. and Mrs. Liu and Feng Sisi looked at the sweet potatoes in a daze since they had never seen anything like it. Still, they instinctively believed Su Binglan.
Feng Sisi asked curiously, "Little Su, can we simply roast sweet potatoes, or do we need to add something?"
Su Binglan said smilingly, "You can simply roast them since they're naturally sweet and fragrant," she removed a few sweet potatoes from her bag as she spoke to Feng Sisi, "Miss Feng, you can roast a few now.
"I think your mother-in-law just lit a fire since the ashes on the stove are still warm. You can put the sweet potatoes into a pot now. You'll know how they taste once you've cooked and eaten them. Also, you can eat these to warm yourselves up when the weather gets cold."
Su Binglan recalled buying roasted sweet potatoes whenever she saw them during the winter in the modern world.
