When nerves surrounding tastebuds are stimulated to signal discomfort to the brain; the chemical sensibility of the skin and mucus membranes.

Question 23

Nerves surrounding the taste buds.

Answer 23

Trigeminals

Question 24

What happens when sugars mixes with saliva?

Answer 24

Sugar draws heat from the mouth and produces a mild cooling sensation.

Question 25

Beside salt and sugar, what else is a good seasoning agent that competes with bitter flavors?

Question 26

Salt used when seasoning meat. Why?

Coarse salt, or kosher, has large grains that are distributed more easily and cling to meat's surface area.

Question 27

When should you season meat with pepper?

Answer 27

Depends. If you want assertive pepper flavor, season meat after searing; keeping pepper away from heat will preserve volatile compounds. Alternatively, seasoning before cooking will tame pepper's punch.

Question 28

Should you season cold foods aggressively?

Answer 28

Chilling foods dulls their flavors, so it's important to compensate by seasoning generously - but judiciously. Season with a normal amount before chilling and then taste and add more salt just before serving.

No, this is why they must be aggressively seasoned.

Question 34

Does aroma affect flavor?

Answer 34

Yes, the aroma that wafts up your nose from a piping-hot bowl of soup affects your perception of flavor.

Question 35

Why do food taste better hot?

Answer 35

Microscopic proteins in our tastebuds that are extremely temperature-sensitive. These proteins, called TRPM5 channels, perform far better at warm temperatures than cool ones.

Question 36

At what temp are TRPM5 channels barely open?

Answer 36

At 59ºF and below flavor perception is minimized.

Question 37

What happens to TRPM5 channels when food is heated to 98.5ºF?

Answer 37

Channels open up and TRPM5 sensitivity increases more than 100 times, making food taste markedly more flavorful.

Question 38

Molecularly, why does hot food smell better?

Answer 38

Much of our perception of flavor come from aroma, which we inhale as microscopic molecules diffuse from food. The hotter the food, the more energetic these molecules are, and the more likely they are to travel from table to our nose.
