Ingredients
- ½ lb Fresh crab meat (lump)
- ¼ lb Fresh shrimp, peeled and deveined
- ½ cup Roasted unsalted cashews
- ¾ cup Heavy cream
- 1 whole Medium yellow onion
- 3 cloves Garlic cloves
- 1 whole Lime, juice only
- ¼ cup Fresh parmesan cheese, finely grated
- 4 whole Crab shells, cleaned and dried (or ramekins)
Instructions
- 1
Place the crab and shrimp on a paper towel and pat them dry by pressing gently until no visible moisture remains, which keeps them from releasing water into the sauce.
- 2
Place the onion root-side down on a cutting board and slice from the tip downward, cutting crosswise into thin half-rings roughly the thickness of a pencil lead.
- 3
Place each garlic clove on the cutting board and press down firmly with the flat side of a large knife until the skin cracks; peel away the skin.
- 4
Mince each garlic clove by chopping it into tiny pieces smaller than a grain of rice — about the size of pencil-tip dots — on the cutting board.
- 5
Pour the cashews and cream into a blender, close the lid, and blend on medium speed for 45 seconds until the mixture becomes smooth and pale, like light pancake batter.
- 6
Heat 2 tablespoons of olive oil in a 10-inch skillet over medium-high heat until the oil shimmers and slides quickly when you tilt the pan, about 90 seconds.
- 7
Add the sliced onion to the hot oil and stir with a wooden spoon once every 30 seconds until the edges turn the color of caramel and the centers soften, about 5 minutes.
- 8
Add the minced garlic to the onion and stir constantly for 30 seconds until the smell becomes strong and sweet, which means it is cooked but not burnt.
- 9
Pour the cashew cream mixture into the skillet and stir with the wooden spoon until combined; reduce heat to medium and cook without stirring for 2 minutes until it starts to bubble gently.
- 10
Add the shrimp pieces to the cream and stir gently with the wooden spoon once every 20 seconds for 3 minutes, until the shrimp turn from translucent gray to solid opaque pink.
- 11
Add the crab meat to the skillet and fold it in gently using a rubber spatula, lifting from the bottom and folding over the top, for 1 minute until just combined and warmed through.
- 12
Squeeze the lime juice into the skillet and stir for 10 seconds; remove from heat and taste a small spoonful, adding a pinch of salt and pepper if needed.
- 13
Set the oven to 400°F and wait until the indicator light or beep tells you it has finished heating, about 10 minutes.
- 14
Place the 4 crab shells or ramekins on a large baking sheet, spacing them at least 2 inches apart so heat circulates around each one.
- 15
Divide the warm crab mixture evenly among the shells, spooning it in until each shell is filled three-quarters full; do not overfill, as the mixture will not expand.
- 16
Sprinkle about 1 tablespoon of grated parmesan cheese evenly over the top of each filled shell, covering the surface lightly.
- 17
Slide the baking sheet into the oven and bake for 8 minutes until the cheese topping turns the color of light caramel and the edges look golden brown.
- 18
Remove the baking sheet from the oven using oven mitts and place it on a heat-safe surface; let the shells cool for 2 minutes so they are warm but safe to touch.
- 19
Transfer each filled shell to a small plate or shallow bowl using a sturdy spoon or tongs, placing it in the center of the plate; serve immediately while still steaming.
