As I mentioned last week, I’ve been building up quite a supply of grapefruit peels of late. Though I will buy lemons and limes throughout the year, for use in jams & preserves, savory dishes and cocktails, I wait for citrus season to roll around each winter to buy citrus for eating and preserving: grapefruits, oranges, exotic varieties. Typically, if I am using a lemon or a lime in a recipe, I’ll use both the zest and flesh or juice; if not, I am in the habit of stripping the zest from the fruit and freezing it for another use. But during citrus season, I build up a lot of citrus peels. And while I love recipes that use the entire fruit (check out this nice roundup, along with a recipe for homemade lemon marshmallows, from Autumn Makes & Does), I eat plenty of fruit out of hand, and there are recipes that just don’t need the bitterness of the white pith. But I can’t bring myself to actually throw the peels away: hence the big bowl of citrus peels, growing ever larger in my fridge.
Once I started thinking about what I could do with all of those citrus peels, and spent a little time researching the topic on the Web, I started feeling guilty that I’ve ever thrown out a peel. There is so much you can do with them! Literally dozens of uses, ranging from food and booze to household cleanser and bug repellant. Peruse the links below for lots of great ideas from around the Web: I may never throw out a citrus peel again!
Of note: I say it all the time, but it bears repeating: if you will be using citrus peel for any edible applications, and especially if you will be extracting the flavor with alcohol, it is best to source organic, sustainably grown, or foraged/wild fruit if you possibly can. In general, the peel of most conventionally-farmed fruits contains the largest concentration of pesticides, fungicides or other chemicals used in treating the fruit. Since citrus peels are not typically eaten in the US, data on pesticide load tends to concentrates on the flesh of the fruit, and is likely an unreliable indicator of pesticide load present in the peel.
What about you: have a great use for citrus peels? If so, I’d love to hear it: please share with us in comments.
Obviously, citrus zest can be used in many recipes, sweet & savory, be it baked goods, stir-fry or stew. But for those recipes where you need the flesh or juice, but not the zest, there are options. I generally strip the zest from lemons or limes, using my handy-dandy Microplane zester, and freeze in small Tupperware or in ice cube trays. Orange zest, however, I find does not keep its flavor on freezing: it will last for a few days in the fridge, but after that loses a lot of its oomph. But I love the ideas for zest and peel below: salt and sugar, butter and oil. Oh, my!

Most liquor infusions call for zest, or only the outside of the citrus peel, leaving behind the bitter white pith. I sometimes find I like the flavor & bite of a bit of bitter pith, plus, I am lazy, so I often just toss the whole peel into whatever I am infusing: vodka, vinegar, white wine. Go with your preference, or try an experiment: infuse two small batches of booze with lemon peel, pith on and pith off. See which you prefer. Also, the recipes you find online almost always call for vodka for infusions, Everclear or grain alcohol for making a liqueur. However, any alcohol can be infused (you should stick with 80-proof and above for liqueurs): how about lime-infused spiced rum? Mixed-citrus silver tequila? Orange-spiked brandy? Once you get the basic, simple concept, you’re limited only by imagination.

I made citrus pectin recently, using the peels from 2 or 3 grapefruits. Based on Julia’s recipe, but slightly modified: I simply tossed my peels, unchopped, in a medium saucepan, covered them with filtered water, and brought to a boil. I let it simmer over medium heat for 10 minutes, then removed from the heat and let it sit, covered, overnight. The next day I strained out the peel and froze the pectin in 1-cup portions. It’s fairly bitter in taste, and would not do for all types of preserves, but for anything that needs a bit of a flavor edge, not to mention a pectin boost, this is perfect.

- Add slivered citrus zest to most any jam or preserve for a little texture & zing: try apple jelly with lemon & lavender (using lemon peels instead of whole lemon slices), sour cherry bam! punched up with lemon zest, orange zest in a cranberry chutney, or lime zest added to blackberry or raspberry jam
- Add chopped candied citrus peel to jams or preserves for another layer of texture and flavor
- Add a strip or two of citrus zest to pickle brine for flavor: see pattypan pickles
- Perk up homemade mustard with citrus zest: see habanero lime chipotle or winter lager mustards
Growing up in a drafty, 100+ year-old farmhouse in New England, the wood stove was the heart of the house come wintertime. My Mom always kept a cast iron kettle on top of the stove, full of water, orange peels, and a few whole cloves. The water added much-needed humidity to the winter air, while the orange peel and clove kept the air smelling fresh, clean, a bit spicy. Simple and effective, like many of the tips below.
