The finishing touch to a million Sunday afternoon desserts, Ideal evaporated milk from Nestlé’s (pronounced ‘Nessles’, never ‘Ness-lay’) brought a dash of creamy richness to any bowl of jelly, fruit cocktail or peach segments. Evaporated milk etiquette demanded that one made a hole in the top of the blue can with a tin opener, before decanting it into a jug. Rivalry came in the shape of Ideal’s nemesis Carnation, prompting a Coke vs Pepsi-style battle of red and blue tins. In the 1980s, evap, as the connoisseurs called it, faced new challenges, not least from Nestlé’s own Tip Top, a Bernard Cribbins-impersonating concoction (‘Whoops-ooh, aren’t you looking slim, mum?’) and, fatally, from Anchor Cream in a can (‘You just go squirt! Squirt! Squirt!’). Sunday teatimes with Jim Bowen and the Man from Del Monte were never the same after that.
