Watermelon and Red Grapefruit Agua Fresca

Grapefruit Watermelon Giulia DoyleI saw this recipe on Sprouted Kitchen the other week. The combination intrigued me because I never thought of making watermelon juice. Why not, I wondered after – the perfect summer juice would be watermelon. Adding the sour notes of grapefruit and the ruby colours combined just made me want to try it even more. So I did on a hot, 30 plus degree Sunday. It was perfect! I had it straight up with ice and lime, Sarah adds sparkling water, which I’ll try next time and her suggestion for margaritas would be great if I was having people over for a summer party.

It’s sour, sweet, cold – perfect on a hot day!
