Rich Pork Pie

Cream turns “improves” into “greatly improves”. The plain pork pie makes healing from other sources faster for a short time; the rich one, by its text, makes it a lot faster for the same short time. Neither heals much by itself beyond the usual boost to health, hunger and hydration. They speed up whatever else is healing you.

That is why the source decides everything. A Large Medkit heals you to max health over time, and a creamy pure healing tea heals a large amount over time. Pair the rich pie with one of those and the extra cream shows. Pair it with a bandage and you mostly paid for a meal.

Picture the tank at Launch Site. A burst catches you in the open, you dive behind a container and start a medkit. With the rich pie already eaten, the bar is back up before the tank swings round again, and you are shooting while the plain version would still have you crouched in cover.

Here is the catch: cream also makes that tea, three to a cup. Brew the tea first. The pie only speeds up a heal you already have, so it is the second place your cream goes, not the first.
