How to make Sour Cream for cake

Quite a few of my cake recipes have sour cream in it. I personally think it gives the cake a nice soft crumb and the sourness blends all the different flavors beautifully.

But as always we end up not being able to make a cake because we don't have sour cream on hand. It is possible to make sour cream for your cake at home.

Ideally you make sour cream with buttermilk but I also make it with lemon juice.

Take 250 ml / 1 cup of heavy whipping cream

Pour in microwave safe bowl or jar.  Heat it up to almost boiling. Leave it to cool until it comes to room temperature. I don't know why but this method works faster for me unlike just warming it up.

Squeeze some fresh lemon juice.

 Add 1 tbsp of lemon juice to the cream
Caution - make sure the cream is room temperature or the lemon juice will split the cream

Cover an leave in a warm place for about 4 hours. I place mine in the oven with the light on.

This is my sour cream after 4 hours.
Ideally you should put this is the fridge to set but for a cake this is good enough and can be used at this time.

I hope this solves the dilemma for some of you especially in India who don't have the option to buy sour cream. (most of the emails on sour cream came from India)
Thanks for stopping by.
