Pomelo Marmalade - a simple 1:1:1 refrigerator marmalade
A few years ago, I impulsively bought an enormous, gorgeously golden, beautifully wrapped pomelo at H Mart. It looked like something you'd ceremoniously present to a duke or a pasha. Like many of my impulse purchases, it sat neglected on the counter for a few days until inspiration struck: marmalade.
I've had a thing for marmalade since childhood, when Paddington Bear convinced me that marmalade sandwiches must be one of life's great pleasures. I remember being shocked the first time I actually tasted the stuff: this was what Paddington was so excited about? Fortunately, I eventually came around. These days there's almost always a jar of Wilkin & Sons marmalade rattling around somewhere in the back of my refrigerator. It probably helps that a lifetime of double IPAs and Negronis has left me with a pretty high tolerance for bitterness.
Pomelo turns out to make excellent marmalade, but it's an awkward fruit to write a recipe for. Pomelos vary enormously in size and among cultivars: some have thick peel and pith, some have heavy membranes, some are virtually seedless and others aren't. A recipe calling for "2 pomelos" is therefore not especially useful.
My solution is to ignore the number of fruits entirely. After trimming the pomelo, weigh the prepared fruit and peel, then add equal weights of water and granulated sugar.
That's it! That's the whole formula:
1 part prepared pomelo : 1 part water : 1 part sugar, by weight.
This is a refrigerator marmalade, not a tested shelf-stable canning recipe.
Ingredients
- 1 pomelo
- Granulated white sugar, equal in weight to the prepared pomelo
- Water, equal in weight to the prepared pomelo
For example, if your prepared flesh and peel weigh 600 g, use:
- 600 g prepared pomelo
- 600 g water
- 600 g granulated sugar
You'll need a kitchen scale, a large pot (I use an enameled cast iron Dutch oven) and a good instant-read or candy thermometer.
Method
- Wash the pomelo thoroughly. Score the rind into quarters from pole to pole, being careful not to cut deeply into the flesh. Peel away the four large sections of rind.
- Moderate the bitterness. Discard two of the four pieces of rind entirely. From the remaining two, use a grapefruit spoon or sharp paring knife to remove most of the thick white pith, leaving roughly 1/4 inch attached to the peel. Pull away and discard the loose pith clinging to the fruit itself.
- Clean up the flesh. Split the peeled pomelo in half along its natural segments and inspect it for seeds. Remove all the seeds. If the membranes separating the segments are especially thick, remove most of them as well, particularly the dense material around the center of the fruit.
Don't become obsessive about this. Much of the useful natural pectin is in the peel, pith and membranes, so we're deliberately retaining some of them. The goal is to moderate the bitterness, not eliminate it.
- Chop the fruit. Give the flesh a medium-fine chop. It will largely break down during cooking, but you don't want enormous pieces of membrane surviving in the finished marmalade.
- Chop the peel. Flatten the two pieces of trimmed rind with your hand and slice them into very fine ribbons with a large, sharp knife. Dice the ribbons. The peel will soften substantially during cooking. The size of the pieces of peel in the marmalade is very much a personal preference - commercial "coarse cut" marmalade with sizable chunks of peel is a real thing.
- Weigh everything. Tare a large bowl on your kitchen scale and combine the chopped flesh and chopped peel. Record the weight.
- Make the 1:1:1 mixture. Put the prepared pomelo into a large, heavy-bottomed pot or Dutch oven. Add exactly the same weight of water and the same weight of granulated sugar. Use a pot with plenty of headroom. The mixture can foam considerably early in the cooking process.
- Soften the fruit. Cover the pot, set it over medium heat and bring the mixture to a boil. Cook for about 20 minutes, stirring occasionally.
- Reduce the marmalade. Remove the lid and continue cooking at a steady medium boil. Do not try to rush with a violent rolling boil. The temperature will initially hover around the boiling point of water and then climb increasingly slowly as water evaporates and the sugar becomes more concentrated.
- Start watching closely around 214–215°F. Stir the marmalade thoroughly with a heatproof spatula or spoon before checking its temperature. Move an instant-read thermometer through several parts of the pot rather than trusting one spot; I've seen readings vary by a couple of degrees within the same batch.
- For a relatively soft, brightly colored refrigerator marmalade, stop at about 216–218°F at sea level—roughly 4–6°F above the local boiling point of water. Traditional jam and marmalade recipes commonly go closer to 220°F at sea level. I've found that taking this particular marmalade that far gives me a firmer set but also a darker color and more cooked or caramelized flavors. I prefer the brighter flavor and jewel-like color I get by stopping a little earlier.
- Cool and refrigerate. Remove the pot from the heat. Once the marmalade has cooled enough to handle safely, transfer it to a clean container, cover and refrigerate. Store in the refrigerator.
- Do not judge the set while it's still warm or even at room temperature. My most recent batch looked decidedly loose after cooling, but after a night in the refrigerator it had set perfectly. Give it at least overnight, and preferably 24 hours, before deciding something went wrong.
A note about bitterness
Even if you love bitter foods, an untrimmed pomelo can produce marmalade that is punishingly bitter. Unfortunately, many of the same parts we're removing—the pith, segment membranes and seeds—also contain useful pectin.
That's why I use only half of the outer peel, trim most but not all of its pith, remove all seeds, and remove only the particularly heavy segment membranes.
Different pomelos will still produce somewhat different results. I consider that a feature rather than a bug.
If it doesn't set
First: refrigerate it overnight.
Seriously. Don't start emergency surgery on room temperature marmalade.
If it's still much too loose after 24 hours, you have several options. You can simply call it a loose marmalade and use it over yogurt, or you can return it to the pot and cook it somewhat further. The conventional gel point for jam without added pectin is around 8°F above the local boiling point of water—about 220°F at sea level.
You could also add commercial pectin or additional acid, but at that point you're modifying the recipe rather than following this particular method. There are plenty of resources on the Internet on how to fix a jam that failed to set.
Did I mention that pomelos vary? Sometimes I've produced a marmalade firm enough that a knife stands upright in it; other batches are softer. I generally roll with the result.
Yield
An approximately 1 lb 12 oz / 800 g whole pomelo produced one quart of finished marmalade in my most recent batch. That's a lot of marmalade!
How I eat it
My favorite use is spooned over thick Greek yogurt. The bittersweet, slightly chewy marmalade is a fantastic contrast to smooth, rich yogurt—and it's also the perfect destination for a batch that happens to come out a little loose.
There's also the obvious Paddington approach: spread it generously on white bread, although long-term storage of sandwiches underneath your hat isn't recommended. Other possibilities:
- In a PB&M sandwich in place of jelly
- In cakes and other baked goods (I have tried it, but the New York Times marmalade cake recipe looks delicious)
- As the sweet component of a glaze or pan sauce for chicken or pork
- Or, radical though it may sound, on toast
