- 2 tsp Unflavored Gelatin (about 7 g, powdered)
- 2 tbsp Lemon Juice (freshly squeezed)
- 1 pinch Salt (fine sea salt)
- 1 large Avocado (peeled, sliced into ½‑inch cubes)
- 8 oz Dungeness Crab Meat (fresh or thawed, gently squeezed to remove excess moisture)
- 1 tsp Lemon Zest (finely grated)
- 2 tbsp Mayonnaise (full‑fat, preferably homemade)
- 2 tbsp Crème Fraîche (room temperature)

Instructions
Blend Watermelon
Place the diced red and yellow watermelon into the blender and blend until completely smooth.
Time: PT5M
Settle and Decant Juice
Transfer the blended puree to a container, refrigerate for 1–2 hours until solids settle. Carefully decant the clear liquid into a clean measuring cup, leaving the sediment behind.
Time: PT1H30M
Prepare Gelatin Mixture
In a saucepan combine the decanted watermelon juice, gelatin, lemon juice, and salt. Bring to a gentle simmer, stirring constantly, until the gelatin fully dissolves (about 3–4 minutes). Skim any foam if needed.
Time: PT5M
Temperature: low simmer
Line the Mold
Lay a sheet of plastic wrap on the bottom of the mold. Lightly spray or dab water on the wrap to help it adhere to the sides.
Time: PT2M
Layer Watermelon and Avocado
Arrange alternating pieces of red watermelon, yellow watermelon, and avocado cubes in the mold, leaving a small gap between each piece for the gelatin to flow.
Time: PT10M
Add Gelatin and Chill
Pour the warm gelatin mixture over the layered fruit and avocado, just enough to barely cover them. Place the mold in the refrigerator and let it set for 1 hour.
Time: PT1H
Prepare Crab Salad
Gently squeeze the crab meat to remove excess moisture. In a mixing bowl combine crab meat, lemon zest, mayonnaise, crème fraîche, and chopped chives. Toss lightly until evenly coated.
Time: PT10M
Unmold and Smooth Edges
Remove the set mosaic from the refrigerator, then carefully lift the plastic wrap and invert the mold onto the serving plate. If desired, heat the edge of a knife or a spoon and smooth the mosaic’s edges for a clean look.
Time: PT5M
Plate and Garnish
Spoon the crab salad onto the center of the watermelon‑avocado mosaic. Garnish with a handful of microgreens for color and freshness.
Time: PT3M

Troubleshooting
Gelatin does not set and remains liquid
Make sure the gelatin was fully dissolved and the mixture was hot enough before pouring; if needed, add an extra ½ tsp gelatin and re‑heat.
Mosaic cracks when unmolding
Run a thin knife around the edges while the gelatin is still slightly soft, and ensure the plastic wrap is smooth to prevent sticking.
Crab salad is too dry
Add a splash of extra mayonnaise or a teaspoon of olive oil to re‑moisten.
Watermelon pieces release excess water
Pat the diced watermelon with paper towels before layering, or let the juice settle longer before decanting.
Storage
Refrigerator: Store leftovers in an airtight container for up to 2 days
Freezer: Not recommended – texture of watermelon and avocado will degrade
Room temperature: Serve within 2 hours of plating
Make-Ahead Tips
- Watermelon juice can be prepared a day ahead and kept refrigerated
