The activity that makes me lose track of time is cooking.

Nothing beats the enjoyment of cooking ever!

But, honestly, the actual cooking isn’t the most enjoyable part of the process.

It’s the preparation of ingredients—putting them in place, arranging them in their special containers, and preparing the bowls for marination.

To make it even more clear:

It’s peeling the carrots that’s enjoyable. 

It’s the knife tearing through the onion and garlic I like

It’s kneading the seasoning to the chicken that’s peaceful.

Every part of the process makes me forget the stresses of my life. It’s because I have to pay full attention to what I’m doing to get the best meal of my life.

So, yeah. To me cooking, no, the preparation in cooking is the one that makes me lose track of time.
