We like the yogurt made with half and half too! It makes it naturally less tart. Like spookyhurst, we add honey. We also put in a bit of legal vanilla. Mmmmm....mmmm...mmmm...
I suggest purchasing the smallest container of honey that you can and give it a try! Our local health food store has honey for sale in bulk (I take my own jars to fill), so I could literally purchase a single tablespoon if I wanted to (though they would look at me like I had three heads!). So perhaps you have something like that available, too, so you're not wasting much if you end up not liking it.
Have you tried putting it in a blender to make a smoothie? We add a little legal juice--usually o.j.--and bananas and honey. That's how my son likes it best.
Do you like cantalope? We chunk the cantalope, add a pinch of salt, then top it off with un-sweetened yogurt. This is awesome!
Best of luck!
