So I decide to go and buy some, but there was the snow, and it was so cold outside that I decide to leave for a different day, but my sweet daughter decided she wants to eat the scones that day so she would ask our neighbor (since she was the one with the original scones and recipe) if she may have some buttermilk she may spare and so she went to the neighbor house and ask her to our surprise she came with a new recipe and apologize for not having buttermilk but explain to us how she never bought it because it was so easy to make your own.
So I gathered some different methods here remembering how my own gram mother used to make it...
The cultured buttermilk; I remember when my grams was running low on Suero she kept always the last cup of it and mix it with a liter of fresh milk, she use to left it at room temperature, now I understand it wasn't the TAPARA in which she used to storage but the Streptococcus Lactic a bacteria that comes in the buttermilk commercial that not only is good for you to obtain the buttermilk but also is good for your stomach like yogurt or at least that's what my gramma used to say
No doubt you may do it in a clean glass jar, as I had done it several times...but this are the Taparas that my gramma use back in Venezuela.
The acid plus milk;
Basically buttermilk is sour milk so mix a cup of milk with one tablespoon of lemon or vinegar, let it sit for 5-10 min is going to curdle....mix it again and you have buttermilk.
With cream of tartar plus milk;
By now you have figure out that the base for buttermilk is milk so we will use one cup of milk and 1 3/4 of cream of tartar, mix it well and let it sit for 5-10 min, when it curdle mix it back and you have homemade buttermilk.
Use as needed and enjoy you delicious Buttermilk.....(insert your dish name here, e.i. pancakes, biscuits, scones etc)........
