Making Home Made Butter.

[Food Fairy]

Hello, 

I received a 2ltr container of double cream from Olio and decided to make some butter.

It worked really well and I got 1kg of butter from 2ltrs of cream plus 750ml of buttermilk.

Now, I always use shop-bought buttermilk when I make scones to get them lovely and light.

The shop-bought buttermilk is sour, like yogurt. The buttermilk from the cream is not. 

Will it work as well in scones or do I need to sour it to get the acid needed to react with the alkaline in the baking powder?

You need to add lemon juice or vinegar to it
