Tips for Baking and How to Avoid Mistakes

How to Use Aluminum Foil for a Moist Finish

Getting your spiral ham moist and juicy depends on how you use aluminum foil. By wrapping the entire ham tightly in foil before baking, you trap the steam and lock in moisture. This helps prevent drying out during cooking and results in a tender finish. Wrapping it in a double layer of foil is even more effective. The general baking time is about 12–15 minutes per pound (about 450g), but ensuring a good seal with foil is key to avoiding overbaking. When applying the glaze (sugar, honey, mustard, etc.) partway through, remove the foil once, brush on the glaze, then loosely rewrap and continue baking. This way, the surface becomes nicely caramelized while the inside stays moist.

How to Check Doneness and Use a Thermometer

To accurately judge when your spiral ham is done, using a thermometer is essential. When the center reaches about 60°C (140°F), it’s ready to eat. This is especially important for bone-in or large hams, where the temperature at the center determines the final result. Insert a meat thermometer into the thickest part of the ham to check the temperature precisely. Since the temperature will rise a few degrees from residual heat, be careful not to overcook. Below is a chart of suggested baking times and temperatures.

Weight (lbs)	Baking Time (min/lb)	Recommended Oven Temp (°C)
7–10	12–15	135–150
10–14	12–15	135–150
Over 14	10–12	135–150

Common Mistakes and How to Fix Them

Common mistakes when preparing spiral ham include drying out, overbaking, and uneven flavor distribution. Here’s how to address each one:

• If it dries out:
  Wrap tightly in aluminum foil to retain moisture during baking. Adding a little water or juice to the bottom of the pan or roaster is also effective.
• If it gets overcooked:
  Check the internal temperature frequently with a thermometer and remove the ham as soon as it reaches the target temperature. Since the temperature will rise from residual heat, take it out of the oven just a bit early.
• If the flavor is uneven or the glaze burns:
  Apply the glaze 20–30 minutes before the ham is done for even sweetness and caramelization. Don’t put on too much glaze at once—apply in several thin layers for even coverage.

By keeping these points in mind, you can make delicious, fail-proof spiral ham no matter what cookware you use.
