Dry aggressively
Thaw completely if frozen, drain and pat the shrimp very dry. If using shell-on shrimp, snip the back and devein without removing the shell.

Big shrimp, a dry surface and very hot grates — grilled just long enough for char, then finished with garlic, lime and herbs after the fire has done its work.

Toss with oil, salt, cumin, paprika and half the garlic. Add lime zest, but save the lime juice for after grilling.
Heat a grill to high and clean the grates. Oil the grates lightly. If the shrimp are peeled, thread them onto two parallel skewers.
Grill 2 to 3 minutes on the first side until charred in spots. Flip and cook 1 to 2 minutes more, just until opaque through the center.
Mix melted butter with the remaining garlic, lime juice and cilantro.
Brush the hot shrimp with garlic-lime butter after they come off the grill. Rest 1 minute and serve with lime wedges.
OPTIONAL UPGRADE
Keep the core recipe clean, or flip this on for one or two high-impact upgrades.
Use these recipe-specific texture cues. Color and curl alone cannot establish safety; use a thermometer to check 145°F / 63°C at the thickest part for cooked shrimp.
The little details that make a big difference.
Surface water and a wet acidic marinade both work against browning.
16/20 or larger gives the grill time to mark the outside before the center dries.
Shell-on shrimp tolerate live fire better and taste more shrimp-like.
Lime juice is best as a finish; it does not make raw shrimp safe and a long acid soak changes texture.
