Boiled Ham Cooking Times by Weight

Below we have listed the approximate cooking times for a Boiled Ham from as small as 500 grams up to 16.5kg based on the simple formula of 20 Minutes cooking for each 500 grams of Ham. (approximately 20 minutes to the lb).

With Joints over 6kg in weight it is advisable to start checking the core temperature with a digital temperature probe after two thirds of the cooking time has past as it possible the actual cooking time may be shorter than indicated by this formula, factors such as;-

  • The heat of your stove
  • The level of boiling, slow or rapid.
  •  How big the joint is
  •  Is it on the bone or off the bone
  • How cold is the joint
  • How long it takes for the water to go from cold to boiling.

These are variables to take into consideration that can’t be predicted in these times below, but the times indicated represent a good starting point to base your cooking time on.

Here we have an example of a Boned and Rolled Smoked Gammon Joint that weighed almost 4kg, it was taken straight from the fridge and was placed in pot, covered with cold water and placed on a preheated stove at 7.30am, exactly 3 hours later at 10.30am the core temperature of the ham had reached 83°C which is as predicted in our list of cooking times below.
