This balances the exigences of cost with the interest everyone has in hot chocolate actually tasting nice. The cocoa gives a chocolate hit, and the cornflour thickens it up nicely.
(for 100 people)
18 pints / 10 litres of milk
12 pints / 7 litres of water (or more milk if you’re not cost-saving)
160g cocoa powder
40g caster sugar
1.2kg supermarket-quality instant hot chocolate powder
- Heat the liquids in a large pan, reserving 200ml milk
- Whisk cocoa, cornflour (this acts as a thickening agent), and sugar, with the remaining milk to make a paste. Add it to the pan while the milk-water mix is still warming up. Whisk to mix.
- When hot, whisk in the hot chocolate powder
- Serve with squirty cream (3 cans) and marshmallows (2 bags)
