The other way around.

Heat and temperature are two quantities that can be easily confused. Imagine cooking a very large pot of
chicken soup on the stove. Letís suppose you heat the soup until it is 95℃, quite hot. ( ① ) You grab a spoon
and take out a spoonful of soup to taste. ( ② ) As you remove the spoonful of soup from the pot, it has the
same temperature as the larger sample. ( ③ ) Unfortunately, as you bring the soup towards your mouth to taste it, the spoon slips from your hand, pouring its contents on your bare foot. ( The spoonful of 95℃ soup hitting your foot hurts, but not as badly as it would if you accidentally spilled the entire pot of 95℃ soup on your foot. ) If both the spoonful and the pot full of soup have the same temperature, why would the larger sample cause more damage if it came in contact with your skin? ( ⑤ ) The answer to the question lies in the difference between temperature and heat.
Does "spoonful" represent "heat" while "pot", "temperature"? Or the other way around?
They are at the same temperature.
The spoonful is a small amount of heat and the pot is a large amount of heat.

They have the same initial temperature. But the temperature of a very small amount of hot liquid will begin to decline quickly with contact with ambient air and contact with tissue. The temperature of the pot liquid will decline much slower.
The text is making the point that, although the spoonful and the pot-full are at the same temperature, the pot-full contains more heat.
If you're familiar with electricity, temperature is analogous to voltage while heat is like power, which is measured in watts.

A spoonful of soup will transfer less heat to your foot than then entire pot will.
I found this:
I remembered physics classes I had when I was a student.
It all comes down to pain in the end.

The difference between heat and temperature is the simple explanation for the seemingly miraculous firewalk. People make a twenty-foot-long walkway covered with red-hot, burning charcoal. After suitable preparation, they are able to walk the whole length of it, barefoot, without burning themselves.
The secret is that, although the coals are at a high temperature, they're not very dense and therefore don't contain a lot of heat. As long as you walk quickly, your feet only touch the hot coals very briefly with each step. The heat can't transfer quickly enough to burn you.
I have a feeling that accomplished firewalkers use only very soft wood to make the charcoal.
