If you need a dairy alternative for cooking & shakes try this:
Mix 1 can coconut milk + 1/2 can water
For baking use this “soured” non-dairy alternative:
To sour the coconut milk mixture place 1 Tb apple cider vinegar in bottom of measuring cup. Now fill to 1 cup mark with non-dairy alternative (the coconut milk + 1/2 can water)
I used this in a cornbread recipe tonight in place of milk & you couldn’t tell.
