In life, everyone may have encountered the scene of tears when cutting onions. This is also the reason why many people are reluctant to make onions. Let me give you some advice.
Cut onions to avoid "spicy eyes";
1. Temperature:
Low temperature: before cutting, put the onion in the refrigerator for a few hours, or in the freezer for about half an hour to reduce the overall temperature of the onion, but it will not freeze. The lower the temperature, the slower the reaction speed of spicy components.
High temperature: If the onion is fried, too high temperature will lead to the gradual denaturation of the enzyme. The production of spicy ingredients is destroyed.
2. Water
Dip some water in the knife and cut the onion. Cut it twice and then dip it in water. Soak onions in water, peel or cut them. Because the irritating gases produced by onions are all soluble in water, salt water and sugar water will be better.
3. The knife should be quick. The irritant substance of onion will only be produced when the cells are destroyed. Too blunt a knife will crush more cells, so it is easier to burn your eyes.
How to choose onions:
The integrity is good, the surface is smooth, and there is a layer of greasy things attached to the surface. Squeeze it tightly, and don't choose to fester or fester.
