Make sure the water is lukewarm or the yeast will not activate properly.Test the yeast first by adding to a bowl with the lukewarm water. If it doesn’t froth, toss the mixture and use a different packet or new yeast.When working with yeast for the focaccia bread, make sure to use lukewarm water. Too hot will kill the yeast and too cold will not allow it to activate.If you want the jiggly bubbles in your Focaccia, poof it overnight in the refrigerator after poofing it once in the Instant Pot. This step is optional. Depending on how much time I have sometimes I poof it overnight, sometimes I don't.
