Become the taste

When eating or drinking, become completely absorbed in the taste, and let it fill you.

The teaching, in plain words
When eating or drinking, become the taste of the food or drink, and be filled with it.
From the Vigyan Bhairava Tantra

How to practice

Choose a small amount of food or a warm drink, and sit down with it. No screen, no reading.
Before the first mouthful, notice the smell and the warmth or coolness.
Take a small mouthful and let all your attention go to the taste.
Let the taste spread and change. Become absorbed in it, as if there were nothing else.
Swallow slowly, pause, and only then take the next mouthful.

You don't need a special meal. A cup of tea or a single piece of fruit is enough to practice this fully.
