Ok, gone for the thinned sour cream option, since it was already sour.

Cake in oven, will let you know if its a disaster!!!!

I did the lemon juice before, it was fine.

Sour cream will work very well, you may need to thin it a little depending on the brand- some are thicker than others.

I'd mix the sour cream with some milk, in a 50:50 ratio.

I always have natural yogurt in the fridge. So useful and not just because I never have buttermilk.

Add one tablespoon of either white vinegar OR lemon juice to a cup of milk and let it stand for about 5 minutes.

I did this recently using the vinagar and the recipe was fine.

sour your milk with lemon juice. 1 tbs to 1 cup

I've gone with lemon and milk before. It worked fine. (was soda bread btw)

Hmm, I have no plain yogurt! I have sour cream, milk, lemon juice and other baking stuff though.

You can use plain yogurt and milk. Half volume yogurt, top up with milk to 3/4 volume of buttermilk. Add that in and then check consistency, if too thick add bit more milk.

I need some for a recipe. Should I use sour cream or should I do the mixing-milk-with-lemon-juice thing. Are either of those any good?
