Flat White at Home

A proper flat white at home: a strong instant-coffee shot under silky, lightly frothed milk, smoother and less foamy than a cappuccino.

The recipe

Exact quantities, then the method.

A flat white is all about the milk: less foam than a cappuccino, just a thin, silky microfoam poured over a strong coffee. With instant coffee the trick is to make it double-strength in a little water, so it holds up under the milk rather than washing out.

Stretch the milk gently, pour it close to the surface, and you get a smooth, glossy cup with barely any foam. Makes one.

6 min Serves 1 Easy Coffee Recipes

You'll need

  • 2 heaped teaspoons of Costa Smooth Medium Roast Coffee granules (about 4g)
  • 60ml freshly drawn water, brought to a rolling boil, then cooled to about 90C (check with a thermometer)
  • 180ml whole milk

Equipment

  • 1 warmed 250ml glass cup
  • 1 small saucepan
  • 1 small handheld milk frother

Method

  1. Warm a cup or small glass with hot water and tip it out.
  2. Dissolve two heaped teaspoons of coffee in 60ml of hot water (around 90C) to make a strong shot.
  3. Heat the flat white milk in a small pan until it steams.
  4. Froth it only briefly, around ten seconds, so you get a thin, silky microfoam rather than the thick foam of a cappuccino.
  5. Pour the milk slowly, keeping the jug close to the surface, so the coffee stays below and a small white dot forms on top.
  6. Aim for silk, not peaks; a flat white wants a glossy microfoam, not stiff bubbles.
What you'll end up with: A smooth, glossy flat white with a strong coffee base and just a thin veil of milk foam on top. Less airy than a cappuccino, with the coffee leading.
