I don't have any knowledge about how to make confectioneries, but I do know that they require more precise control than normal processed foods.

What is especially important is the amount of material, which they says should be measured precisely in grams.

Also, the slightest change in temperature or time can completely change the taste of the finished pastry.

My junior daughter told me that among the various sweets, "macarons" are extremely difficult to make.

From what I've heard, there are lightly more than 10 parameters that affect the taste of macarons, and it seems that these parameters are not independent variables.

The term "not independent variables" means that the variables influence each other, and in short, the optimal solution cannot be obtained linearly.

This means that the amount of ingredients, mixing ratio, combustion temperature, heat release time, outside temperature and humidity, and other factors that make macarons perfect are not easily determined.

"Making macaroons is like an NP-hard problem in mathematics"

(That's my interpretation) my junior daughter talked about it that way.

"And yet, that guy who insists on homemade macaroons for Valentine's Day is an idiot?"

She was cursing her boyfriend all the time.

Yes, now I understand my second daughter's indignation.

Ebata: "You are absolutely right. Those who don't understand the difficulty of the task, and who comfortably make demands of others, deserve the ultimate punishment.

Ebata: "I'm also thinking, 'Is that guy stupid enough to think that adding human psychological states to an NP-hard Dial-A-Ride problem, and then solving it in real time, is 'easy'? That's what I'm thinking!

The two of us, father and daughter, continued to scream in anger at the unreasonableness of the world.
