Vanilla Steamer and Babyccino

Before you start

A steamer is the simplest café drink: hot, frothy milk sweetened with a little syrup, usually vanilla. A babyccino is its smaller, cooler cousin, a cup of milk foam for children, often dusted with cocoa and sometimes served with a marshmallow. Neither contains coffee or tea, so both work any time of day.

With so few ingredients, texture and temperature are everything. Milk tastes sweetest around 55°C to 65°C (130°F to 150°F); hotter than that, it starts to taste flat and cooked. For a child, aim even lower, warm rather than hot, so the drink can be enjoyed right away. You do not need an espresso machine: a saucepan and a jar, a French press or a cheap handheld frother all make good foam.

Ingredients

• 300 ml (1¼ cups) whole milk — cold from the fridge
• 10 to 15 ml (2 to 3 tsp) vanilla syrup — or 1 tsp sugar plus ¼ tsp vanilla extract
• 1 pinch ground cinnamon or cocoa powder — for dusting
• 2 mini marshmallows — optional, for a babyccino

Method

1. Pour the cold milk into a steaming pitcher, filling it no more than a third full so the milk has room to expand. If you are not using a steam wand, pour it into the saucepan.
2. Steam wand: dip the tip just below the surface and open the steam fully. Let it draw in air with a soft tearing sound for 3 to 5 seconds, then sink the tip a little deeper so the milk spins. Stop at about 60°C (140°F), when the pitcher feels hot to hold.
3. Stovetop: warm the milk over medium-low heat to about 60°C (140°F), steaming but not bubbling. Pour it into a French press and pump the plunger 15 to 20 times, or into a jar, sealed with a towel over it, and shake for 30 seconds, until it has doubled in volume.
4. Tap the pitcher or jar on the counter and swirl it to pop large bubbles and give the foam a glossy, wet-paint look.
5. Add the vanilla syrup to the mug and pour the milk over it, letting the foam settle on top. Stir once and dust with cinnamon.
6. For a babyccino, stop heating at about 45°C to 50°C (113°F to 122°F), when it feels warm but not hot. Spoon the foam into small cups, dust with cocoa, and test the temperature yourself before handing it to a child.

Tips for success

• Start with very cold milk. It gives you more time to build foam before it reaches temperature.
• Whole milk makes the creamiest, most stable foam. Lower-fat milk foams higher but drier and collapses faster.
• Barista versions of oat milk are designed to foam; regular cartons often stay flat.

Substitutions

Vanilla syrup

Caramel, hazelnut or maple syrup all work. Honey dissolves best when stirred into the hot milk, not added to a cold mug.

Whole milk

Oat barista milk gives the closest texture to dairy. Soy milk foams well but can split if overheated; almond milk produces large, loose bubbles.

Cinnamon dusting

A little grated nutmeg or cocoa adds aroma without sweetness. Skip it for very young children who might cough on fine powder.

Variations

Hot chocolate steamer

Whisk 1 tbsp cocoa and 1 tbsp sugar into the mug with a splash of hot milk before adding the rest.

London fog-style steamer

Steep a bag of rooibos or decaf Earl Grey in the hot milk for 4 minutes, then froth and add vanilla.

Troubleshooting

The milk will not foam

It was too warm to start, too low in protein, or already heated before. Use fresh, cold milk and introduce air early, while it is still cool.

The foam is big and bubbly

Too much air too fast. Keep the wand tip just under the surface rather than above it, and swirl and tap the pitcher before pouring.

It tastes cooked or flat

It was overheated. Stop at about 60°C to 65°C (140°F to 150°F), when the pitcher is hot but you can still hold it for a few seconds.

Storage

Steamed milk does not keep; make it to order. Do not reheat milk that has already been steamed, since it will not foam again and tastes flat. Return the unused milk carton to the fridge promptly.

Safety notes

Hot milk and steam can scald. Always check the temperature before serving a babyccino to a child, and keep steam wands and pans out of reach of small hands.
