Why it works: Ham and beef are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 1,729 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

Meat Canning

Ingredients

Directions

Prepare

  1. Cure hams in mild sweet pickle for 30 days, repacking in new pickle as needed.

  2. Bone the hams.

  3. Trim excess fat, leaving a slight covering.

  4. Wrap the skin back over the ham.

  5. Bind it tightly with twine.

Cook and fill

  1. Place hams in heated water at 180°F (82°C) for 14½ hours, then remove them.

  2. Place them hot in cans filled with jelly made from boiling beef bones.

  3. Seal the cans while still hot.

Process and seal

  1. Process in a retort at 5 lbs pressure for 14½ hours.

  2. Open vents with a fine awl after processing.

  3. Close vents when pressure is off.

  4. Return cans to the retort.

  5. Heat for another 1½ hours at 9 lbs pressure.

  6. Open vents again.

  7. Quickly solder them shut.

  8. Cool the cans in a shower room.

What each ingredient does

Hams
Provides the main meat, whose texture is set by curing and gentle heating.
Mild sweet pickle
Salt and sugar cure the meat, seasoning it and helping it keep.
Beef bones
Release gelatin as they simmer, which sets into a jelly that moistens the ham.

The step that matters

Retort processing at pressure. The sealed cans must be held at the stated pressure and time in the retort. Heat at this level destroys microbes that survive ordinary cooking, so a shortfall in time or pressure can leave the sealed ham unsafe.
