pourable
Able to flow smoothly when you tip the container.
Pourable describes something liquid or loose enough to flow smoothly when you tip its container. Pancake batter is pourable when it's thin enough to stream from a mixing bowl onto a hot griddle. Honey is pourable at room temperature, but it gets thick and barely pourable when cold. Sand is pourable because the tiny grains slide past each other easily.
The word helps us think about consistency, which is how thick or thin something is. Peanut butter isn't pourable because it's too thick and sticky. But if you melted it, it might become pourable. Yogurt sits somewhere in between: some yogurts are thick and spoonable, while others are thin and pourable enough to drink.
When cooks say something needs to be pourable, they usually mean it should flow but not be watery. Cake batter should be pourable enough to spread evenly in the pan. Salad dressing should be pourable so it coats the lettuce instead of sitting in globs. The term is especially useful in recipes and instructions, where getting the right consistency can make the difference between success and a sticky mess.
