How to Prepare and Cook the Shrimp Perfectly

Shrimp Selection

Type

Best Choice

Why

Size

Large (21-25 count per lb)

Substantial bites that don't overcook quickly

State

Raw, peeled, deveined

Full control over cooking; saves prep time

Fresh vs Frozen

Thawed frozen

Most reliable quality; flash-frozen at peak

Thawing Method

  • Place frozen shrimp in colander under cold running water for 5-7 minutes
  • Pat completely dry with paper towels before seasoning
  • Never use warm water or microwave - causes rubbery texture

Seasoning Process

Step

Action

Timing

1

Toss shrimp with Old Bay, garlic powder, salt

Right before cooking

2

Drizzle with olive oil and lemon juice

30 seconds before pan

3

Let rest at room temp

5 minutes max

Cooking Technique

  • Heat skillet over medium-high heat until hot
  • Add 1 tbsp oil - should shimmer immediately
  • Arrange shrimp in single layer without crowding
  • Cook 1-2 minutes per side until pink and opaque
  • Remove when centers are just turning white - carryover heat finishes cooking

Slightly firmer texture, golden edges

Quality Checks

Grainy texture

High heat or adding cheese too fast

Start over; low heat is critical

Curdled sauce

Acid addition or extreme heat

Strain through fine mesh, add cream

Too thick

Over-reduced

Add milk, 1 tbsp at a time

Too thin

Not enough roux

Mix 1 tbsp flour with 2 tbsp milk, whisk in

Greasy surface

Not enough emulsification

Slowly whisk in splash of cold butter

Perfect Sauce Indicators

  • Coats back of wooden spoon thickly
