Lime can slow browning but does not prevent it indefinitely. Fresh lime juice has no label to check; if you use bottled juice, check its label. Chips and dipping vegetables are separate quantities.

Check the exact products you buy, especially flour, oats, bread, pasta, sauces and broth. Gluten-free labeling and third-party certification are different. A recipe page or scanner cannot guarantee a dish’s preparation. Use clean equipment and protect ingredients from contact with gluten-containing foods. Gluten-free does not mean free of dairy, eggs, nuts or other allergens. See the FDA guide to gluten-free labels.

Use a food thermometer and the safe cooking temperature chart. Refrigerate perishable food within two hours, or one hour above 90°F, in shallow containers as appropriate. Keep the refrigerator at 40°F or below. Use refrigerated cooked leftovers within 3–4 days; reheat cooked leftovers to 165°F. See USDA leftover guidance.
