Yes, lobster gender matters—at least for flavor. Female lobsters often have slightly sweeter meat, plus you get the bonus of roe (the bright red coral) or tomalley (the greenish liver), which some consider the best part. Males tend to have larger claws.
For steaming, a 1¼- to 1½-pound lobster is the sweet spot. Bigger lobsters (over 2 pounds) can get tough if you’re not careful, so stick to the medium range for that buttery, fork-tender result.

If you’re feeling adventurous, steam a dozen lobster tails for 4 minutes per 4 ounces. Perfect for tacos or a decadent pasta toss without the full-claw commitment.
