I now realized that actually setText() is called for the server
Ingredient-entity. But I'm not sure if that helps me, since the Recipe
instance does not know anything about the Ingredient-instance on which
that happens. But I guess that's more an Objectify-problem then. Maybe
I'll switch to JDO for now.

Thanks anyway,
Tobias
