Add rack and minimum amount of water for cooking to Instant Pot liner. I use a 6-quart so I used one cup of water.
Place stainless steel cups into the pot on top of the rack.
Add 2 tablespoons of vinegar to each cup.
Add 6-7 drops of food dye to each cup or up to 10-12 drops.
Top each cup off with enough water to color the eggs.
Cook using the 6-6-6 method. This means 6 minutes at high pressure, a 6 minute NPR, and a 6-minute ice water bath.
Decorate as needed. Serve immediately, or store in the refrigerator for up to one week.
Notes
Note: You can reuse the dye to make additional batches of eggs. Allow the pot to cool for a few minutes. Be sure to add more water to the inner liner so you have the minimum amount for your pot for cooking. Add more food dye if needed. Add six more eggs to the cups, and just be sure there is still enough water to cover them. Repeat the remaining directions.
