Potion of porridge
|A filling potion of sludge, high in cereal fibre.|
Quaffing a potion of porridge increases your satiation level by 6,040 points. This is regardless of dietary preferences, with the one exception being that pure carnivores (ghouls, kobolds, and anything else with the Carnivore 3 mutation) receive no benefit from them whatsoever. Unlike other potions, potions of porridge are always identified on sight.
That potion was really gluggy!
Prior to 0.14, potions of porridge were identified on sight, but could be guessed at because they would always be described as "gluggy white" or "gluggy brown" potions. Also, they only gave 6,000 nutrition (though all potions gave a base 40 nutrition at the time, making it add up to the same benefit).
