can dried orange peel be reconstituted?

I would say no. I have never heard of adding water to fresh orange peel and certainly not dried. It is meant to be used in baking.

McCormick Gourmet Lemon Peel does not contain gluten. Gluten and gluten products, when present, will always be declared on the product label by the common name of the gluten source such as “barley”, “wheat”, “rye”, “oats” or “triticale”. If no ingredient statement appears on the product label, then the product is as it appears in the product name (e.g. black pepper). It is important that you read the ingredient statement on your package at the time of purchase to ensure accurate, up to date information, as product formulas may change. If any product has a Gluten-Free claim, the product and the manufacturing line has been validated Gluten-Free. McCormick takes the safety and quality of our products very seriously and you can be certain that we exercise the utmost care in the production and packaging of our products. Our employees are trained in the importance of correct labeling and the necessity of performing thorough equipment clean-up and change over procedures to minimize cross-contact of ingredients. ~ Erica
