Substitute for Hated Sour Cream

I absolutely HATE sour cream. Can't stand either the taste or the smell. Both make me gag! And yes, I can usually taste/smell it, if it's in there! I also don't like cream cheese - it's a texture thing. Is there any consistant substitute for s.c, in baking especially? I've used plain yoghurt, but is there anything else I can use across the board?
