How to Cook Onions until Translucent
Why does my onion look translucent?
When cut, onions are typically translucent. This means that the skin is thin and easily visible without needing to be peeled. The opacity of onion skin can be explained in a few ways. First, onion cells are dichotomous–they have an outer layer of cells that are round and hard, and an inner layer that is more like a sheet of paper. When onion cells divide,
they create two layers of cells (the upper layer being called the pericarp). The pericarp divides into many small cells, each of which contains one or several onion bulbs. These small cells create the opacity of onion skin. Second, onion skin has a secretions called glycoproteins. These glycoproteins help keep the cell walls tough and protect the interior from damage by bacteria and other organisms. Finally, when onions mature, their cell walls break down and their water content decreases.
How long till onions become translucent?
There is no set time frame for when onions will become translucent, but the process can typically take anywhere from a few weeks to a month. While there are no guarantees, it’s best to wait until onions have grown some new roots and started to produce their characteristic yellowing/turning color before trying to peel them.
What happens to onion when its cooked?

That’s because other factors play a role as well. One of which might be the way the onion is cooked.

Different types of onions turn a different color when dehydrated, according to some scientists.

When this happens, the bright colors that onions display are caused by a high level of reactive oxygen species (ROS).
Why do leeks go pink when roasted?
Leeks are a dark green and go pink when roasted. It is likely that the color is due to anthocyanins, which are pigment molecules that are produced during the roasting process.
