Have you ever wondered what watermelon could taste like as jam? This recipe started with a simple observation while peeling a watermelon for a salad, the aroma.
It was sweet but with a hint of grassy freshness, something I’d never fully noticed before. So, instead of tossing out the rinds, I thought, why not simmer them down and make jam?
The result? A fresh, bright jam that feels like summer in the middle of winter. The subtle sweetness and cool, clean flavor of watermelon turn into a spread that’s unexpected, delicious, and perfect for more than just toast. It’s a way to capture those fleeting summer moments and preserve them for later.

Behind the Recipe
This watermelon jam was born out of the idea of preserving summer’s sweetness in a jar. Instead of just enjoying watermelon fresh, I wanted to find a way to hold onto that flavor for when the weather isn’t as warm. Simmering down the watermelon with sugar and a little lemon creates a jam that’s light, refreshing, and a fun twist on traditional fruit preserves.
