ometimes you have to get creative with your glassware. In this video, I test whether it's possible to pour high-quality latte art inside a hollowed-out watermelon. The Verdict: The shape acts like a wide bowl, which is actually great for Rosettas. The taste? Well, that's a different story. The Challenge: Vessel: Half a Watermelon (hollowed) Design: Classic Rosetta Difficulty: 9/10 (The fruit juice makes the milk unstable!) #watermeloncoffee #latteartchallenge #weirdcoffee #barista #rosetta #summer
