Mosaic Heart Jello Jigglers

Mid-May 2024. The apartment is on the kind of Sunday that arrives slow and stays that way. Brayden is two years and eight months old. He has reached the small stage of toddlerhood where he picks his own snacks from a small drawer I have set up at his height in the pantry — goldfish crackers, raisins, a small bag of cut grapes from Saturday’s grocery run, the small box of rice cake pieces I keep for the mid-morning small-snack-window.

The pregnancy is at thirty-seven weeks. Full-term. The hospital bag is packed and sitting in the front closet. The car seat is installed in the back of my Civic. The nursery is set up. The freezer is at the small-fifty-meal-portion-bank we have been building since March. Mama drove up Friday afternoon to start her small late-pregnancy ten-day stay. She is sleeping on the office daybed.

The mosaic heart jello jigglers are a small-Sunday-afternoon-project for Brayden — small heart-shaped jello cutouts in pink and red and blue, arranged into a small mosaic pattern in a clear glass casserole dish. The project is part-craft, part-snack, all-toddler-engagement. The project filled the small Sunday-afternoon window between Brayden’s lunch and his small late-afternoon nap.

The technique on jello jigglers is the firm-jello-set. The standard four-cup-of-water-per-package ratio makes a wobbly jello that does not hold its cut-shape. The jiggler-version uses one-and-a-half cups of water per package, which gives a firm-enough set to hold a clean cut. The jello chills for at least three hours before cutting.

Prep Time: 30 minutes | Cook Time: 0 minutes | Total Time: 4 hours 30 minutes (includes chilling) | Servings: 24 jigglers

Ingredients

1 box (3 oz) strawberry Jello
1 box (3 oz) raspberry or cherry Jello
1 box (3 oz) orange or lemon Jello
3 cups boiling water, divided (1 cup per color)
3 cups cold water, divided (1 cup per color)
2 envelopes (1/4 oz each) unflavored gelatin
1/2 cup cold water (for unflavored gelatin bloom)
1 cup boiling water (for white layer)
1 can (14 oz) sweetened condensed milk

Instructions

Make the colored Jello layers. Prepare each box of flavored Jello separately: dissolve each in 1 cup boiling water, stir 2 minutes until fully dissolved, then stir in 1 cup cold water. Pour each color into a separate shallow 8×8-inch dish or rimmed baking sheet. Refrigerate all three until completely firm, at least 2 hours.
Cut into cubes. Once firm, use a sharp knife to cut each colored Jello slab into small 1/2-inch cubes. Gently remove the cubes and place them together in a large bowl, mixing the colors loosely. Refrigerate the bowl of cubes while you prepare the white layer.
Prepare the white condensed milk layer. Sprinkle both envelopes of unflavored gelatin over 1/2 cup cold water in a large bowl; let sit 2 minutes to bloom. Pour 1 cup boiling water over the bloomed gelatin and stir until completely dissolved. Stir in the sweetened condensed milk until smooth and well combined. Allow the mixture to cool to room temperature — it should not be warm when it touches the Jello cubes or they will melt.
Combine and pour. Lightly spray a 9×13-inch baking dish with nonstick cooking spray and wipe out any excess. Scatter the colored Jello cubes evenly across the bottom of the dish. Slowly pour the cooled white layer over the top, gently pressing any floating cubes down so they are submerged and distributed throughout.
Chill until fully set. Refrigerate uncovered for at least 2 hours, or until the white layer is completely firm and the jigglers hold their shape when touched.
Cut into hearts. Run a thin spatula around the edges of the dish to loosen. Press a heart-shaped cookie cutter firmly through the set Jello, cutting as many hearts as possible. Use the spatula to lift each heart out cleanly. Gather any scraps — they are cook’s privilege.
