Watermelon

Summer, contained in a rind.

92% water, rich in lycopene (more than tomatoes, gram for gram), and full of citrulline — an amino acid for circulation.

Watermelon has been the world's most efficient summer cooling device for about 5,000 years. 92% water, ice-cold when chilled, and sweet enough to make a heatwave feel survivable. Ours are thumped, checked, and hand-picked for peak ripeness — which is an art, not a science. Eat it straight, juice it, salt it, or cube it with feta and mint for a salad that punches above its weight.
