What's the most impressive thing about a cup of coffee?

In my spare time, take the book to the coffee shop and order a hot latte. The most enjoyable thing is the moment the hot coffee is served, the strong aroma of the coffee is accompanied by dense milk bubbles, and in addition, there is an amazing pull flower.

The principle of flower drawing

The English word for coffee flower is Latte Art, which, as its name implies, is the art of latte, which uses milk foam to paint on coffee. The base of a typical Lafayette coffee is Espresso (espresso). This is because Espresso has a thick layer of oil (Crema), which produces enough surface tension to hold up milk bubbles made of tiny bubbles. Through the arrangement of milk bubbles and oils, a variety of patterns can be made, so in addition to the barista's skills, milk bubbles and coffee oils are also very important factors for the success of flower drawing.

The prerequisite for the success of flower drawing is that the substrate has sufficient surface tension, so not only coffee can be made, but general water is also possible to be successful. But the difference is whether it tastes good (or can you drink it) and whether you can make a beautiful pattern.

Coffee flower drawing needs to be prepared.

Coffee: 1 cup dosage-7g brew 30c.c espresso (Espresso) with espresso machine

Milk foam: a cup of milk with a dosage of-160c.c, beat into 250--300c.c

Objective: the volume of milk becomes more and lighter, it can float on the surface of coffee, the taste is dense, and it can be shaped by flowers.

Principle: usually can be divided into two steps

Get rid of: air into the milk, so that the milk coated with air foaming into a small foam-

Beating: the foamed milk is making use of the whirlpool to beat the big bubbles into small bubbles, making the milk bubbles more dense--

Tools:

Electric hand beater: it is convenient for home use, like a blender for baking, but the milk foam is not dense.

Filter kettle: like making tea, pressing it into the air with your hand, what a waste of leftover milk

Hot and cold electric milk foam machine: the milk foam is too dense and thick, suitable for traditional cappuccino, not suitable for flower drawing

Italian coffee machine steam foam: no manpower, temperature and pressure can be adjusted

Flower drawing step

1. Extracted coffee

First prepare the coffee base Espresso, and then start to foam, because the foam structure will disappear after a long time.

two。 Pour the right amount of milk into the steel cup.

A seemingly simple step is actually the first step in successfully making a good foam. The volume of milk expands when it turns into foam, so there can't be too much milk, so there is enough room to heat the milk to form foam. Milk is usually poured to the bottom of the V-shaped cup mouth.

3. Release steam

Before putting the steam stick into the flower pot, turn on the steam and let the water at the front end of the steam stick release, otherwise if too much water runs into the milk, it will affect the fineness of the milk foam.

4. Foaming

The main purpose of this step is to pump air into the milk so that part of the milk forms milk bubbles. Place the steam stick on the surface of the milk and turn the steam to the maximum, which should produce a squeak. Control the amount of foam according to the type of coffee until there is enough foam to stop foaming.

5. Mix

When there is enough foam, insert the steam stick into the bottom of the milk and let the milk begin to rotate so that the upper foam mixes with the lower layer of milk. When the temperature reaches 70 degrees, the steam can be turned off, and the milk foam used to pull flowers is finished.

The ideal drinking temperature of milk is 70 degrees. If the temperature is too low, the whole cup of coffee will not be hot enough and affect the taste. If the temperature exceeds 70 degrees, it will destroy the structure of the milk and make the milk lose its sweetness.

6. Pull flowers

Before the milk foam is separated from the milk, pour the milk into the Espresso so that the coffee and milk are fully combined. When the cup is 6 or 7 minutes full, draw the figure directly through the shaking of the cup and steel cup.
