See the making of icing in [this video](https://youtu.be/BDe5zxH7qV8?t=77).

> Using a hand mixer beat the coconut oil, lemon juice, apple cider vinegar, vanilla extract and 1 cup of powdered sugar to start. Once it's mostly combined add in another cup of powdered sugar and beat together. Then add in soy milk and beat until smooth and fluffy. Then ice the cake!

I'm worried that there's some kind of mistake and this will impact the flavour for no reason. Should I leave out the vinegar? Add baking soda? Leave the recipe as is?
