The Surprising Edibility and Health Benefits of Watermelon Rind
While most people enjoy the sweet, red flesh of a watermelon and discard the thick outer rind, this practice overlooks a surprisingly versatile and nutritious food source. Watermelon rinds are perfectly safe and edible, offering a mild, cucumber-like flavor when raw and a firm, squash-like texture when cooked. Beyond being a smart way to reduce food waste, the rind is packed with health benefits that make it a valuable addition to your diet.
Nutritional Powerhouse
Don't let the pale color fool you; watermelon rind is brimming with beneficial compounds. It contains significant amounts of fiber, which is crucial for healthy digestion and can help lower cholesterol. It's also a rich source of the amino acid citrulline, which has been linked to improved athletic performance and better blood flow. In fact, the rind can contain a higher concentration of citrulline than the fruit's flesh. Additionally, the rind provides vitamins A, C, and B6, along with important minerals like potassium and magnesium.
Preparing Watermelon Rind for Consumption
Before eating, always wash the watermelon thoroughly under running water, scrubbing the green skin to remove any dirt or bacteria. Most people prefer to use the white part of the rind, peeling away the tough, dark green outer layer. However, the green skin is also edible, particularly if you grow your own pesticide-free melons.
To prepare the rind:
- Peel: Use a vegetable peeler or a sharp knife to remove the outermost green layer.
- Trim: Cut away any remaining pink flesh from the white part of the rind.
- Chop: Dice the white rind into cubes or slice it into matchsticks, depending on your recipe.
Ways to Eat Watermelon Rinds: Raw vs. Cooked
Whether you prefer a fresh crunch or a tender bite, there are many ways to prepare watermelon rind.
Raw Preparations
- Salads and Slaws: Dice or julienne the rind and toss it into salads for a fresh, crisp texture similar to jicama or cucumber.
- Smoothies: Blend the chopped rind into your favorite smoothie for added fiber and nutrients. The mild flavor won't overpower other ingredients.
- Gazpacho: Blend raw rind with other vegetables like cucumber and tomato to create a cooling, hydrating summer soup.
Cooked Preparations
- Pickled Rind: A classic Southern preparation, pickling the rind with vinegar, sugar, and spices transforms it into a tangy, sweet condiment.
- Stir-fries: Slice the rind into strips or cubes and add it to stir-fries. It holds up well to high heat and absorbs the flavors of the sauce.
- Curries: Use the rind as you would a vegetable like squash or zucchini in a curry, allowing it to soak up rich spices.
- Candied Rind: Boil rind chunks in a sugar syrup with spices like cinnamon and cloves for a nostalgic, chewy candy.
- Roasting: Toss rind cubes with olive oil and seasonings like salt, pepper, and parmesan cheese before roasting at 400°F (200°C) until tender and browned.
Comparison: Raw vs. Cooked Watermelon Rind
| Feature | Raw Watermelon Rind | Cooked Watermelon Rind | 
|---|---|---|
| Texture | Crunchy, similar to a firm cucumber or jicama | Softer, more tender, similar to squash or tender carrot | 
| Flavor | Mild and neutral, easily takes on other flavors | Absorbs the flavors of the cooking liquid, spices, or seasoning | 
| Preparation Time | Very quick; just wash, peel, and chop | Longer, requiring simmering, roasting, or pickling time | 
| Versatility | Excellent for salads, smoothies, and cold preparations | Ideal for savory dishes, pickles, and sweet preserves | 
| Nutrients | High in fiber and citrulline, retains heat-sensitive vitamins | Fiber and citrulline remain, but some vitamins may be reduced | 
| Common Uses | Slaw, smoothies, gazpacho | Pickles, stir-fries, curries, candy | 
Potential Considerations
While generally safe, eating large quantities of rind at once can cause digestive upset for some people due to its high fiber content. It's best to introduce it gradually into your diet. For those purchasing non-organic melons, peeling the green outer layer is recommended to remove any potential pesticide residues.
