I think orange peel has to go into boiling water to bring out the flavor . I think that's why it's done during the boil. The extract may work . One thing you might wanna do during a brew is set all your stuff out on the counter in line as to when its added . I've only been brewing for a yr or so and it can be a tad overwhelming. Heck I forgot to check my SG before I pitched the yeast the other day cuz I was so excited to do my first all grain batch. We learn as we go .
