This kind of bread cannot be made into Sandwiches however.
You don't need to learn any new recipes to make Gingerbread loaves, instead you can bake them by selecting the one basic recipe for all kinds of Breads in the Cooking Station.
Then insert (as of R35 in October 2016):
- 1x Molasses that can be obtained as a rare drop from either Arctic Mirus, Blizzard Chizzards or Rambeau, multiplied by letting it flow and then scooped up without needing any Power Cells
- 4 bundles of Wheat grown on tilled soil near Water from Wheat Seeds, found when harvesting Tallgrass (and/or Savannah Tallgrass)
When consuming a Gingerbread Loaf (by putting it into a quickslot, choosing that quickslot and clicking your right mouse button or by dragging this food over your character's model on the right side of the inventory) your character will be granted a bonus of 100 points to their maximum Health for 7 minutes and 30 seconds (as of R35 in October 2016).
Only one Gingerbread Loaf of a whole stack will automatically be consumed if you use a stack. If you eat more Gingerbread Loaves (by right-clicking or dragging & dropping again) than one after another, the effect of raising maximum Health will merely set/prolonged to 7:30 minutes anew.
