Frozen hot chocolate

The name is a contradiction and the method explains it: real chocolate is melted hot, then blended with ice. Skipping the hot step is the single reason home versions fail.

beginner

Frozen hot chocolate is a blended iced drink whose chocolate content is genuinely melted chocolate rather than syrup, and the hot step is not optional. Chocolate is a suspension of solids in cocoa butter; it disperses into a liquid only when the fat is molten and something emulsifies it. Blending solid chocolate with ice produces exactly what it sounds like — cold chocolate shrapnel in milky water.

So the method is: melt the chocolate into a small quantity of hot liquid, build a smooth emulsion, cool it, and only then blend with ice and milk. The result sits between a milkshake and a granita, and it holds its texture for a few minutes rather than indefinitely.

What it is for
To make a blended frozen drink that tastes of melted chocolate rather than of cocoa.
Does not work with
Cocoa powder alone gives a thin, icy drink with none of the character this preparation exists for. If you are using powder, you are making an iced chocolate, which is a good drink and a different one.

Ratios

ForRatioNote
Frozen hot chocolate1:5 chocolate to milk, plus ice by volumeRoughly 40g chocolate to 200ml milk, plus about a cupful of ice. Stronger than a hot drink at the same volume, because ice dilutes and cold suppresses.

Method

  1. 1. Melt the chopped chocolate into a small quantity of hot milk — around 60ml per 100g — whisking to a smooth, glossy emulsion.

    Where people go wrong: Using too much liquid at this stage. A thin mixture will not emulsify properly and the fat separates as it cools.

  2. 2. Cool the base completely. Refrigerate it if there is time.

    Where people go wrong: Blending it warm, which melts the ice on contact and gives a lukewarm thin drink.

  3. 3. Blend the cold base with cold milk and ice until smooth but still frozen.

  4. 4. Serve immediately. This drink has a working life of a few minutes.

When it goes wrong

Hard flecks of chocolate through the drinkMelted chocolate met something cold before it was emulsified and cooled gradually.Build and cool the emulsion completely before it goes near ice. A stick blender makes a much more robust emulsion than a whisk.
Separates into ice and liquid within a minuteNot enough fat or solids to hold the structure, or over-blending.More chocolate, whole milk rather than skimmed, and a shorter blend.
