i love to cook lumpia. for the longest time i cook it with papaya and camote. but recently, i tasted one using singkamas and i love the texture.papaya when cooked was smooth…tastes good also but i like the recent discovery…singkamas.for the benefit of some who are wondering where to add peanut butter, i use it in making the sauce in case i do not have toasted peanut available.i’ll try to cook your spring rolls wrapper recipe to compliment my lumpia.we use to eat it as is with the sauce not wrapped.more power miss connie!i’m a fan!
