This recipe looks SO gross, and is so much fun. The general idea is based off of one by Better Homes and Gardens. This one comes from the fabulous site, Divine They stacked their shrimps in a glass bowl and used a more basic gelatin recipe. This version of this very gross Halloween food is Cajun flavored and prepared in a Jell-o brain mold instead of a bowl. And it looks a little too realistic for comfort!
Serves 10-12.

~3 lbs. shrimp, peeled, cooked, deveined
~2 small roasted red peppers, julienned
~1 green onion, sliced into 2" pieces, then julienned

Gelatin Mixture:
~2 1/2 C. chicken broth
~1 1/2 tbsp. (1 1/2 envelopes) unflavored gelatin
~1 tsp. lemon zest
~1/4 C. fresh lemon juice
~1/2 C. tomato paste
~3 cloves minced garlic
~1 tbsp. honey
~1-2 tsp. Cajun seasoning
~Pinch salt

1. Into a purchased jello brain mold, layer your shrimp in, tails facing the middle of the brain. It's best if you layer them into the brain mold with the tails facing the middle, according to each "hemisphere" of the brain. This will give you the most realistic look. Tuck the shrimps in close together.

2. Drop bits of roasted pepper and green onion in around the shrimp. These should look like veins and nerves when you're finished.

3. Repeat, alternating between shrimp and vegetables, until you fill your Jello brain mold.

4. Now make the gelatin. In a small saucepan, bring the chicken broth to a boil. Remove from heat and stir in the unflavored gelatin.

5. Stir in the lemon zest, juice, tomato paste, garlic, honey, cajun seasoning, and a pinch of salt (the amount will depend on how much salt is in your Cajun seasoning-- mine's salty so I don't use much).

6. Pour this mixture over the shrimp in your brain mold, filling to the top. Discard any extra. With a rubber spatula, smooth the top of your shrimp and gelatin to create a smooth surface.

7. Refrigerate until firm, at least several hours.

8. To unmold, set your Jell-o brain mold in a bowl of hot water for a few seconds. Place a serving tray underneath, then flip your mold over. The brain should pop right out. This is one of the easiest gross Halloween foods to make in advance! Maybe serve with fava beans and a glass of Chianti.
