Watermelon Granita
Watermelon is the king of our summer; we eat it cold in the afternoon to chase away the heat.
Here we turn it into granita, refreshing ice crystals that melt in the mouth and quench thirst.
Blend the watermelon flesh in the blender until it becomes a smooth liquid. Remove the seeds first so they don't leave a bitter taste.
Pass the blended watermelon through a strainer to separate out any fibers or small seeds. Straining gives a smooth texture to the ice crystals.
Add the honey and lemon juice and stir well. The lemon brings out the sweetness of the watermelon and keeps the taste from turning flat. Watermelon is naturally sweet, so we use only a little honey.
Pour the mixture into a wide, shallow-rimmed tray and place it in the freezer for an hour. A wide surface freezes the mixture faster and makes it easier to scrape.
Every half hour, take out the tray and scrape the frozen surface with a fork to turn it into ice crystals, then return it. The sign of readiness is that the whole mixture turns into separate ice crystals, not a solid block.
Repeat the scraping three to four times over two to three hours until the entire mixture becomes even ice crystals.
Scoop the granita into chilled cups and garnish with mint leaves. Serve immediately before the crystals melt.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.
* Percent Daily Values are based on a 2,000-calorie diet per FDA food-label reference values — your daily needs may be higher or lower. Values are derived from the recipe's ingredients via the USDA database.
The most common problems when preparing Watermelon Granita, and how to fix them:
Take it out and let it soften a little, then scrape it firmly with a fork, and stick to scraping every half hour next time.
Chill the cups in the freezer before serving and serve immediately after scooping.
Add another splash of lemon juice, as it wakes up the watermelon flavor.
Strain the watermelon a second time through a finer sieve before freezing.
It keeps covered in the tray for up to a week; scrape it with a fork before serving to restore the crystals.
If it has set too firmly, leave it for a few minutes at kitchen temperature, then scrape it again.
