Full Fat Yogurt Substitute

I ended up doing an experiment. I tested the lowfat on a bit of the chana masala. It did curdle, so I ended up using the sour cream.

I think lowfat (yogurt) has a greater tendency to curdle when heated. I would say full fat greek yo or sour cream would be fine

low fat yogurt

I would use full fat sour cream although I am sure a reduced fat yogurt would work just fine also. You could also mix a little full fat sour cream with low fat yogurt if you wanted the full fat effect.

So I can't edit this--but I need a sub for the yogurt. Would you use full fat sour cream or low fat greek yogurt? I also have a couple cans of coconut cream, milk, full fat buttermilk, and plain kefir. Which dairy sub would you use?
