No-Frills Shrimp Boil

Preparation

1. Step 1

   Combine potatoes, 1/4 cup Zatarain's, several large pinches of salt, and 5 quarts water in a large stockpot. Cut 1 lemon in half crosswise and squeeze juice into pot, then toss in halves. Bring to a boil, reduce heat, and simmer, uncovered, until potatoes are fork-tender, 20–25 minutes.

   Step 2

   Add corn to pot; increase heat to high and bring liquid back to a boil. Add shrimp, cover pot, and turn off heat. Poach shrimp until just cooked through, about 2 minutes. Immediately pour entire contents of pot into a large colander to drain, then spread out corn, potatoes, and shrimp on a large rimmed baking sheet or sheets of newspaper; discard lemon halves. Sprinkle with more Zatarain's and drizzle with oil. Cut remaining lemon into wedges and serve alongside for squeezing over.
