Detailed production of siphon pot
Siphon coffee pot always has a little mystery in most people's impression. Siphon coffee pot played an important role in the history of coffee development in Taiwan Province. In recent years, so-called ground coffee (espresso) has become popular. In contrast, this siphon coffee pot needs high technology and complicated procedures, and it has gradually declined in today's industrial and commercial society where every second counts. However, the siphon coffee pot can brew coffee with a general fragrance.
Most people often have a little knowledge about this and even have a wrong impression. Usually, there are two extreme views. One is that some people are wary of it, and what is the other? In other words, the siphon coffee pot is just to boil the water and stir the coffee powder. In addition, some people think that siphon coffee pots look dangerous. In fact, as long as the operation is improper, every method of making coffee has hidden dangers.
Several points should be paid attention to when making coffee with siphon coffee pot: water quantity, water quality, heat, dosage and thickness of coffee powder, stirring and time, which are explained below.
Step 1: Pour hot water until the glass falls, and boil it with high fire until the water boils.
When cooking one cup, the amount of water to be added is 200cc, and it needs 175cc without pouring the bottom water, and it needs 350cc when cooking two cups. After pouring water, dry the ball under the glass with a rag, otherwise it will easily break the glass. ※.
Step two, put the filter in the ball.
Take the filter screen out of the water, clean it, press it dry, hook the hook of the filter screen on the bottom of the ball, and then adjust the position of the filter screen to the middle position with the adjusting lever. ※.
Step 3, after the water boils, insert the upper ball into the lower ball.
Turn the heat down, carefully put the upper glass ball into the lower glass ball obliquely, and when it is confirmed that the water will not roll out too much, press the upper glass ball down slightly and rotate at the same time. ※
Step 4: After the water rises to half, add coffee powder, start stirring, and start counting after stirring.
Dosage per cup15g, start the first stirring. Don't turn around when stirring, draw three-quarters of a circle from left to right, and press the powder into the water from top to bottom, so that two forces in different directions collide with each other. Don't stir for too long, just let the coffee powder disperse. ※.
Step 5, stir for the second time in 25 seconds.
Step 6, stir for the third time in 55 seconds, and turn off the fire in 60 seconds.
It only takes 50 seconds to make a cup of coffee (20 seconds for the second time and 45 seconds for the third time). After turning off the fire, quickly pull up the top ball, pour out the remaining water from the bottom ball, and then insert it back into the top ball. This action is called pouring water. If you don't want to do this step, you just need 175㏄.
Step 7, wipe the glass ball with a wet and cold towel immediately after turning off the fire.
Step 8: When the coffee liquid is filtered to the end, pull up the ball on the cup and don't let the last coffee flow down.
