The internal temperature of the shellfish should reach 145°F (63°C).Look for The sauce will be bubbling gently and the seafood will be tender.Safe temperature 145°F (63°C) internal temperature (shellfish)Tip Check the temperature with an instant-read thermometer inserted into the thickest part of a scallop or shrimp.
- Stir GentlyUsing a slotted spoon, gently stir the seafood and vegetables in the butter sauce to coat everything evenly. Be careful not to break up the scallops.Look for The sauce should be glossy and the seafood should be well coated.Tip Stir gently to keep the scallops whole.

When serving, the seafood should be coated in a glossy chili lime butter sauce, with the vegetables distributed throughout. The rice should be fluffy and ready to absorb the delicious sauce. The lemon wedges add a bright, citrusy finish. The dish looks vibrant and inviting.
Common mistakes
One common mistake is overcooking the seafood, which makes it rubbery. Stick to the recommended cooking time and check for doneness early.
Another mistake is adding too much salt, as the butter and seafood already have natural saltiness. Taste the sauce before adding extra salt. Also, avoid stirring too vigorously, which can break up the scallops.
How to tell it’s done
The dish is done when the scallops are opaque and firm to the touch, and the shrimp are pink and curled.
The internal temperature should read 145°F (63°C) on an instant-read thermometer inserted into the thickest part of a scallop or shrimp. The sauce will be bubbling gently and the vegetables will be tender but still have a slight crunch.
