British strawberry jelly is a fruit-flavored gelatin dessert, similar to what is known in the United States as Jell-O. Not a jam or fruit spread as the term "jelly" might indicate in the States, British jelly is a beautiful, fruit-forward, and refreshing dessert that can take elaborate forms and be decorated with intricate fruit arrangements. Home cooks usually make this common dessert using a store-bought concentrated flavored gelatin block, which requires only to boil some water—similar to making powdered Jell-O.

The authentic British version, however, uses fresh fruit, sugar, gelatin, and water, such as in our traditional recipe. We chose fresh summer strawberries, but any fruit of your choice that's ripe and sweet, and perhaps in season, will work well. Decorate with fresh fruit, use animal shape molds for little party treats, or make a whole jelly to display as a centerpiece.

Delicious on its own, it goes amazingly with whipped cream, ice cream, or custard, which is a classic dish on the tea-time table. A budget-friendly dessert, this is a great dish for family affairs during hot days and is fun to eat. Layer two or more flavors for an extra treat or use our recipe for a more elaborate and elegant English trifle. If you're planning ahead, be mindful that the jelly needs at least two hours to set, but leaving it in the refrigerator overnight is always best.

Ingredients

  • 1 cup (200 grams) superfine sugar

  • 2 1/4 cups (675 milliliters) water, divided

  • 1 pound (500 grams) fresh strawberries, gently washed

  • 1/4 ounce (11 grams) plain unsweetened gelatin powder

Steps to Make It

Note: While there are multiple steps to this recipe, this jelly is broken down into workable categories to help you better plan for preparation and refrigeration.

Make the Syrup

  1. Gather the ingredients.

Make the Strawberry Mixture

  1. Set aside 4 or 5 of the fresh whole strawberries and hull the remaining fruit by removing the entire stems of the berries.

  2. Purée the hulled strawberries with an immersion blender, highspeed blender, or food processor until you've achieved a smooth texture.

Prepare the Fruit Jelly and Refrigerate

  1. Make sure the remaining water is cold and pour it into a small dish. Sprinkle the powdered gelatin over and let sit for 5 minutes.

  2. Measure 1 cup of the strained strawberry-sugar syrup mixture and heat it up in a small saucepan.

  3. Stir in the gelatin-water mixture and simmer very gently, avoiding a boil, until the gelatin has completely dissolved.

  5. Transfer the strawberry mixture to a 3-cup/900-ml gelatin mold or into individual smaller molds if you'd like.

  6. Place the mold in the refrigerator and let set. This will take a couple of hours but it is best to leave it overnight. The jelly is ready when it wobbles slightly—the fun part of the dessert.

  7. To unmold, carefully dip the mold in warm water for 15 to 20 seconds and remove. With wet fingertips gently pull the jelly from the sides of the mold. Place a plate on top of the mold and turn the plate and mold upside down so the jelly falls on the center of the plate. Decorate with the strawberries you saved and enjoy!
