Frequently Asked Questions About Fresh Watermelon Juice
Do you have questions about making our fresh watermelon juice?
Yes, it makes the blending and straining process much easier and smoother. But if all you have available has seeds you can pulse instead of just running the blender to keep them more intact, and then strain them out.
Fresh is best for flavor, but bottled works in a pinch.
Nope! A blender and a big spoon for stirring are all you need.
