How do I store leftover Grilled Citrus-Marinated Swordfish Steaks?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep (6 oz each) swordfish steaks from drying out.

Can I substitute ingredients in Grilled Citrus-Marinated Swordfish Steaks?

How do I scale Grilled Citrus-Marinated Swordfish Steaks for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
