Introduction

Reheating leftovers is a cherished Mexican tradition, especially during Christmas and New Year’s celebrations. However, this practice is often accompanied by numerous mistakes in the kitchen. This guide aims to clarify how many days it’s safe to consume popular dishes like turkey, cod, quelites (a type of succulent plant), leg of lamb, and apple salad without compromising food safety.

The misconception that “if it still smells good, it’s good to eat” is one of the most dangerous myths in December cooking. Bacteria do not always announce their presence with bad odor or taste.

General Safety Measures

  1. Keep your refrigerator at 4°C or lower.
  2. Only reheat the portion you plan to consume.
  3. Avoid reheating the same dish multiple times.

Apple Salad

Safe consumption time: 24 to 48 hours

Ironically, apple salad is one of the most delicate dishes to reheat. The combination of fresh fruit, sugar, and dairy products creates an ideal environment for bacterial growth, even when refrigerated.

  • Storage tips:
    • Store in airtight glass or food-grade plastic containers.
    • Avoid leaving it on the table for hours “for dessert.”
    • Do not mix new portions with old leftovers.
  • When to discard: If it shows signs of acidity, separation of liquids, bubbles, or a runny texture.

Turkey

Safe consumption time: 3 to 4 days

Turkey, when properly cooled and refrigerated, can withstand time better than most cooked meats. The main threats are dryness and cross-contamination.

  • Storage tips:
    • Debone and divide into small portions.
    • Store with a little of its own juice or broth.
    • Keep it separate from raw foods in the refrigerator.
  • Ideal reheating: Heat evenly, covered, until hot in the center. Reheating the same piece multiple times increases health risks.

Cod

Safe consumption time: 4 to 5 days

Cod is a resilient candidate for reheating. The salt, oil, and prolonged cooking act as natural preservatives, provided it’s kept consistently cold.

  • Storage tips:
    • Store in an airtight, completely covered container.
    • Use clean and dry cutlery when serving.
    • If frozen, it can last up to two months without losing structure or flavor.
  • Ideal reheating: Low heat and patience. The microwave tends to overheat the oil and break up the fish.

Leg of Lamb

Safe consumption time: 3 to 4 days

Whether adobada, roasted, or glazed, the lamb follows the same rules as other cooked meats. Sweet sauces, however, can accelerate spoilage if not refrigerated properly.

  • Storage tips:
    • Slice only what you plan to consume.
    • Keep the piece covered and slightly moist.
    • Do not leave it at room temperature “for the sandwich.”
  • Ideal reheating: Oven or skillet, covered. Microwave only if you add moisture and monitor time.

Quelites (Succulent Plants)

Safe consumption time: 2 to 3 days

Quelites are one of the most complex dishes to reheat, as they involve quelites, mole, dried shrimp, and potatoes in a moist environment that can deteriorate rapidly.

  • Storage tips:
    • Refrigerate as soon as they cool.
    • Do not add fresh broth to a previously stored preparation.
    • Avoid constant stirring.
  • Warning signs: Spontaneous bubbling, sour odor, or color change. Discard if any of these signs appear.

Final Consideration: Knowing When to Say Goodbye

In domestic gastronomy, the most common error is trying to “extend” food due to attachment or waste. However, no dish is worth the risk of food poisoning.

If there’s any doubt, if the time is up, or if something seems off, the responsible decision is to discard it.
