What does 且 mean by itself? I was watching Blur's new music video, which includes a recipe for ice cream with instructions in Chinese.  (https://www.youtube.com/watch?v=Sp1ks7PTzng)  At 3:03, the recipe says '将奶黄放入一个大，浅且可置于冷冻库的容器'.  I don't really understand how to translate this part.

Also, how would you translate ‘即可离火'?  This is in the recipe at 2:59.  Does it mean something like 'immediately take away from the heat?'

Many thanks.
将奶黄放入一个大，浅且可置于冷冻库的容器 means 'put the custard into a huge, shallow container (and) which can be put into a freezer'. 

So here 且 means and(而且).

Another useage 且 means 'just', such as 且行且珍惜(just cherish what you have at the moment) here 且 means just.

即可(离火) means you can do something when something happen as soon as possbile.

Such as: 
1. 当油热了，即可离火 (When the oil is hot, you can turn off fire right now[She suggest you do it right now]).
2. 开袋即食 (Open the bag, you can eat it)

即 has a meaning of you can do something with a hint do it now(as soon as possible).
