A new market stall that would be used to sell liquid/stew to other players.
Not sure if this idea has been tossed around yet or not. It is a different type of market stall that just dispenses liquid/stew. The stall could show the liquid color and/or the food bits inside. The stall could be a barrel with a viewport/window in the side to see what the stall contains. You throw your money in like a regular stall, then you turn a spigot which will dispense one flask worth of liquid.
