An exothermically hydrated fuel for a self-heating food container comprises particles of a hard quicklime that has been calcined at a temperature above 1,400 DEG C., such as from 1,410 DEG C. to 1,500 DEG C. The fuel can also contain at least 10% based on the weight of the hard particles of softer, more porous particles of quicklime calcined at a temperature above 1,250 DEG C. and/or particles of an anhydrous acid that exothermically reacts with quicklime to form a non-toxic, non-hazardous salt such as oxalic acid.
