I thought of Langka preserve. I would have wanted to make candies (candied langka) but the weather has not permitted for it will entail sun drying.
The preserve turned out to be really good. Try this recipe:
4 cups water
4 cups white sugar
1 piece lemon
grated rind of 1 piece lemon
1 tablespoon vanilla
1 tsp. cinnamon
Let it stand overnight.
Let it cool. Line the bottles with wax paper before sealing.
Refrigerate. The preserve is good for 2 weeks only. Great as ice cream topping or mix in special halo-halo, filling in homemade waffles or spread unto buttered toast..
