While many liquids exist that serve as an alternate to milk for the lactose intolerant, I'm wondering to what extent can butter melted and mixed with water serve as a milk substitute, even if an imperfect one. Specifically I'm considering drinks, such as coffee, hot chocolate. Drinks that often don't require cream of milk but which personal preferences often include adding some or replacing water with it.
If I'm out of almond milk or non-lactose creams for my coffee, would mixing in a little butter make it creamier?
If I'm making hot chocolate and want it creamier than when made with just water, would a little butter help?
I've read questions on here that there is limited success mixing buttermilk and butter to get cream but it doesn't work for all uses, but that seemed to be focused on baking and whipping cream and not drinks.
