Step 1

Set up a steamer for the crabs. The steamer insert should sit 2 to 3 inches above the bottom of the pot so that the crabs do not touch the liquid beneath.

Step 2

Add 1 1/2 cups water, lager, vinegar and 2 tablespoons seafood seasoning to the bottom of the pot. Whisk to combine and bring to a simmer.

Step 3

Layer the crabs in the steamer insert, generously sprinkling the salt and remaining seafood seasoning on each layer of crabs.

Step 4

Cover the pot and steam the crabs for 30 minutes. The cooked crabs should be a bright orange color throughout with no trace of blue or green.
