A Tommy cooker was a compact, portable stove, fuelled by something referred to as solidified alcohol which was issued to British troops (Tommies) in World War I. It was notoriously ineffective; one soldier complained that it took two hours to boil half a pint of water. A variety of commercial or improvised alternatives were in use.

A refined version remained in use during World War II, using gelled fuel in a tin can; a steel ring fitted to the can supported a mess tin.
The British army still uses compact portable solid fuel (hexamine) stoves.
The term also came to be applied by the German tank crews as a derogatory nickname for the Sherman tank whose earlier models acquired a reputation for bursting up in flames when hit, due to improper ammunition storage.

Tinned Heat - solidified methylated spirits'Tinned Heat' was a little round tin pocket stove, or 'Campaigner's Cooker'. Only 3½ inches in diameter and 1½ inches high, it contained solidified methylated spirits. It was deemed to be perfectly safe, quite practical and absolutely efficient; an ideal arrangement for a soldier's use in the trenches. If anything could be pronounced ideal in those circumstances. 'Tinned Heat' cost 10½d each.
Canned Heat - Sterno solidified alcoholInvented around 1900, Sterno is made from ethanol, methanol, water and an amphoteric oxide gelling agent, plus a dye that gives it a characteristic pink color. Designed to be odorless, a 7 oz (198 g) can will burn for up to two hours. The methanol is added to denature the product, which essentially is intended to make it too toxic for consumption, thus the British term 'Methylated Spirits'.
The British cookers were made by Tommy's Cooker Co., Limited, The Little Kitchener Co. and the "Pals" Cooker by Matthias Jackson & Sons.
