Be sure to have a kitchen thermometer, without it it is difficult to prepare syrup.
Ingredients: water, sugar, citric acid, baking soda
Cooking method:
We take a saucepan and, as I wrote, add all the ingredients in turn. The main thing is that nothing gets on the walls of the saucepan. Pour in water and carefully pour sugar and at this stage add citric acid, do not mix anything.
We put the saucepan with syrup on low power and bring our mass to 108 °. WE DON'T INTERFERE ANYTHING, just hold the thermometer. When the syrup has reached the desired temperature, add soda and carefully remove the saucepan from the heat, soda is needed to neutralize the acid.
We wait until all the foaming soda cap disappears. If suddenly the cap does not disappear for a very long time, put and warm up a little syrup and gently move along the bottom with a wooden spatula.
The syrup should be like honey, beautiful, slightly golden or creamy. Store in a cupboard or refrigerator in a closed glass container.
There will be a little more foam, but you wait, the syrup should be clear, not cloudy. If there are still transparent bubbles on top and the same in the syrup, it's okay, pour the syrup into a jar, glass and cover with a lid or foil and let stand, the bubbles will disappear after a while.
