The bill is paid in hunting. Fifty low grade fuel goes into every bottle, and that fuel is mostly animal fat, so a stack of molotovs starts with a few kills out in the woods. Cloth tops the calculator, but a small hemp patch covers it.
The fuel is also the slow part: nearly all the craft time is fuel crafts, while the bottle itself is quick. Fuel needs no bench, so craft it from your inventory between farming runs and the molotovs come off the Level 2 bench in moments. Make them in pairs. One bottle leaves a little fuel over, two use the batches exactly.
Every drop here is fuel the explosives don't get. Early in a wipe that costs nothing, since nobody has Level 3 yet. Later, spend fuel on molotovs only when the box has some to spare.
