Hot chips - What does the word "hot" mean in this phrase?

Solution 1:

In Australian English the word "chips" refers both to deep fried thick strips of potato, normally served fresh and hot and called French fries in US English, and to thin slices of potato cooked until they are crisp, usually bought in packets and called "crisps" in UK English. "Hot chips" especially on a market stand sign would almost always refer to the freshly fried ones. The word "hot" is used on a sign to claim that they are fresh enough to retain their heat.

Note that many Australians distinguish French fries as having a smaller cross section than normal chips.

Also note that the linked picture clearly shows strips, so they are not crisps.
