How do you tell if a citrus fruit has wax on it before zesting?

Question

Not sure if your citrus has wax on it? Learn a few simple ways to tell so you can be sure to wash it properly before you begin to zest.

Answer 1

Look for a shiny, slightly sticky surface on the citrus fruit. You can also gently scrape the peel with your fingernail; wax will often come off as a white or translucent residue.

Detailed Explanation:

Many citrus fruits are coated with wax to extend their shelf life and improve their appearance. This wax coating, while generally food-grade, isn't something you want in your zest, as it can affect the flavor and texture of your dish. Here's how to check for wax:

1. Visual Inspection: Examine the fruit under bright light. Waxy fruits often have a noticeable sheen or shine that natural, unwaxed fruits lack.

2. Touch Test: Feel the surface of the fruit. Waxy coatings can feel slightly sticky or slippery to the touch.

3. Scratch Test: Gently scrape the surface of the peel with your fingernail or the edge of a knife. If wax is present, you'll likely see a white or translucent residue accumulating under your nail or on the knife.

4. Water Test: Place a drop of water on the peel. If the water beads up and doesn't spread out, it suggests the presence of a hydrophobic (water-repelling) wax coating.

Pro Tip:

If you suspect your citrus fruit has wax, thoroughly wash it with warm water and a scrub brush before zesting. For extra precaution, you can blanch the fruit in boiling water for a few seconds, then scrub it. This helps to remove the wax more effectively.
