Answer:
Cucumber
Step-by-step explanation:
Cucumbers have the highest water content of any food, at around 96%. A medium-sized cucumber weighs about 200 grams.
Butter contains around 15-20% water. A standard stick of butter contains approximately 20.4 grams of water.
Commercial butter is about 80% butterfat and 15% water. Traditionally-made butter may have as little as 65% fat and 30% water.
