Rose,
one of the stores that we shop in carry a line of products which are called 'Greenwise'
and all of their products are 'organic' and very affordable...
we just put in a jar the amount of oats we want for different consistancies,
such as:
we will put 2cups of oats in a half a gallon of water, this makes a real good broth -
but (1) cup per half a gallon of water makes a good refreshing drink, also it is
very, very soothing to the stomach -
sometimes we like to add fresh ginger or a little honey for a bit of sweetness -
the size of the jar you use, you simply adjust the proportions to it...
oh yes, we also sometimes make 'barley water' using the same formula, it's
quite healthy-tasty and has been around for hundreds of years...
