Can you make whipped cream with half and half? If you can, what, if anything, do you have to do differently?
I occasionally want a pure food additive for various reasons (pure potassium chloride for sports drinks, pure MSG for everything), but I can't find any decent places to get them except amazon.com. Now ...
I make a lot soups and various stews and they don't seem to last more than a few days - are there any natural preservatives that can be added to them that will increase their refrigerator life?
