Boiling longer helps because the thicker it is (more mucilage) the better it holds together. That said, I only boil mine for ten minutes. Then I add a tsp of aloe vera gel (Lily of the Valley), vitamin e oil, and agave nectar and all of those together seem to make it more jelly like and increase hold. So does marshmallow root. I throw a tsp of that in with my flax seeds as I boil. Some people mix their hard hold gels with FSG. You could do that in your palm. Oh you could also substitute the agave with honey. Add more than I do for increased hold.
