A whisk made for one job
The molinillo is a carved wooden stick with a bulbous, grooved head, often with one or more loose rings carved from the same piece of wood. It is used almost exclusively to froth hot chocolate and some other warm drinks. The name comes from Spanish, from the word for a small mill, which reflects the way it is twirled. Whisks of similar design are known in other parts of Latin America, and the molinillo is often associated with Mexico and with the long tradition of drinking chocolate there.
The shape is distinctive. A long handle, held above the pot, widens into a carved head with rings and grooves. The head sits in the liquid, and the handle stays in the cook’s hands.
How it froths
The molinillo is not stirred like a spoon. The handle is held vertically between the palms, as if rubbing the hands together to warm them, and rolled back and forth so the head spins quickly in the liquid. Some cooks also move it up and down a little. The carved grooves and loose rings churn the liquid, trap air, and break it into small bubbles, which build up as foam on the surface.
The loose rings are usually not just decoration. They rattle and spin against the head, adding extra agitation. The foam is the main point of using one: it gives the drink a light, airy top and helps the chocolate, sugar, and spices blend.
What it is used with
Traditionally, a molinillo is used with chocolate that has been made by grinding roasted cacao with sugar and sometimes cinnamon or other spices. This type of tablet, discussed in the article on stone-ground chocolate, does not dissolve completely, so the whisk is needed to bring it together. The tablet is melted in hot water or milk, and the whisk is then spun until the drink is foamy and smooth.
The same technique can be used for warm corn drinks. Thicker atoles and chocolate champurrado, for example, are sometimes frothed this way, as they too can separate or form a skin. The molinillo is not typically used for coffee or cold drinks.
Basic technique
A simple approach, with no exact quantities required:
- Warm water or milk in a tall pot, without letting it boil hard. Boiled milk is prone to scorching and boiling over, and chocolate can turn bitter if scorched.
- Add broken pieces of chocolate and stir until they soften and melt.
- Place the molinillo in the pot, with the handle through the hole in the lid if the pot has one, or held clear of the top.
- Roll the handle between your palms steadily until a thick foam forms, a minute or two.
- Serve straight away, since the foam fades as the drink cools.
Use a tall, narrow vessel so the liquid is deep enough to be churned without splashing. Hold the pot steady, and stay careful of hot splashes. A jug or a dedicated chocolate pot (a chocolatera) is traditional, and its lid often has a hole sized for the handle.
Materials and craftsmanship
Molinillos are typically carved from a single piece of wood, and hardwoods are common. The carving can be plain or elaborately decorated. Some are painted, which is fine for display, but a whisk used in hot food should be unpainted or finished with a food-safe coating. Handmade versions vary between regions and makers, and the price and quality can vary too.
Care
Wash the whisk in warm water as soon as possible after use, using a soft brush for the grooves, and do not soak it or put it in a dishwasher, which can crack or warp the wood. Dry it completely, standing upright if you can, and store it in a dry place. Wood that stays damp can grow mould. Discard a whisk that has splintered or cracked deeply.
Modern alternatives
Electric frothers, small handheld whisks, and blenders can produce a foam as well, and many people use them for convenience. They are quicker and easier to clean. The molinillo is slower but is appreciated for the ritual, the sound, and the connection to older ways of preparing chocolate. Neither approach is wrong, and the choice depends on what you value.
A note on drinks: Traditional hot chocolate is sweet and often contains sugar and, sometimes, milk, so it is best enjoyed in moderation, and anyone with allergies should check the ingredients of any tablet they buy.
