Add the butter sticks to the inner pot of the Instant Pot.
Select the Sauté function and allow the butter to melt completely.
Continue cooking uncovered as the butter bubbles and the moisture evaporates.
No need to stir the butterfat while it is cooking.
Watch as the milk solids settle at the bottom and gradually turn golden brown. This will happen at the 12 minute mark if you are using 8 sticks of butter
Once the butterfat looks clear and golden and the milk solids develop a nutty aroma, switch off the Instant Pot.
Allow the ghee to settle briefly, taking care not to let the residual heat burn the milk solids.
Let the ghee cool a little bit.
Carefully strain the ghee through a fine-mesh strainer lined with clean cheesecloth into a heat-safe container.
Let the ghee cool completely before securing the lid.
Store in a clean, dry, airtight jar away from moisture and heat, or refrigerate if preferred.
