My brother and I used to sell these around the neighborhood when we were kids. Our mother cooked it. These sweet potatoes slices were fried in oil with caramelized brown sugar. Then skewed in bamboo sticks. There would be around 3-4 slices in each sticks and will be then sold. We visited homes and even shouted "Hot Camote Cue for sale." Each stick was 1 peso and we always come home empty handed but with a pocket filled with pesos. Those were the days. So every time I cook these, I remember it. Wants me to shout again "Hot sweet potatoes everyone?"
