One vegetable I love to pair with langka is pallang (winged bean). They'll be a great combination for a dinengdeng especially when lightly soured with kamatis or salamagi. Pallang as a solo dinengdeng soured with salamagi is also a favorite.
|A "native" pallang.|
|Another variety (hybrid) of pallang called "puraw a pallang" ("white pallang")|
And here's my dinengdeng a langka ken pallang. I cooked it somewhat dry with just a little but very tasty and delicious broth. The immature seeds of langka is sweet (the mature seed of the ripe fruit, meanwhile, is also edible and makes a great merienda when boiled, it tastes nutty like peanut):
Great with steamed rice suffused with a little cooking/palm oil!
