Sounds Like Tea - NATO.
Take a green norgie container, add a large handfull of NAAFI teabags, a bucket of sugar and half fill with boiling water. top off with milk (So about 50:50).
Leave to stew for 7 or 8 hours (while still maintaining the near boiling temp).
Serve on a cold, wet gun position.
Absolutely vile but its hot and wet.
