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.
Caution - make sure the cream is room temperature or the lemon juice will split the cream
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.
Thanks for stopping by.
