What each ingredient does

Marrow or pumpkin
Forms the body of the preserve, providing its bulk and mild, sweet flavour.
Sugar
Adds sweetness and helps the preserve taste balanced and rounded.

The step that matters

Tightening the lids after cooling. As the hot mixture cools, the air inside contracts and creates a partial vacuum that seals the jar. Lids tightened only while hot may be pushed off by pressure, and once the glass has contracted the lids must be retightened to keep the seal secure.
