Best Quick Grapefruit Marmalade Recipes

GRAPEFRUIT MARMALADE

Steps:

• Bring a large, covered pot of water to boil with the whole citrus fruit. This Cuisinart pot from Amazon is a decent size for the job. Boil the fruit until they are very tender and soft. Grapefruit take about 2.5 hours. Drain the fruit and let them cool slightly before proceeding.
• Place a cutting board inside a rimmed baking sheet (these Nordic Ware sheet pans from Amazon are great). This is to catch all the citrus juices! Slice each fruit in half to expose the seeds. Remove the seeds if there are any, then quarter each half. Seperate the flesh from the peel so that you can slice the peel thinly and chop the flesh, removing any membranes if they are tough. Transfer the sliced peel, flesh, and juices into a large pot (like this Cuisinart pot from Amazon).
• To the large pot of chopped fruit, add the sugar and the lemon juice. Clip on your thermometer (like this fast-reading digital thermometer from Thermoworks). Bring the mixture to a boil on medium-high, stirring with a wooden spoon or heatproof spatula (grab this spatula from Amazon). When the mixture is boiling, this is when you want to start monitoring the temperature. Boil the mixture, stirring constantly, until it reaches 220°F (104-105 ºC). When the marmalade reaches this temperature, slide the pan off the heat, and let it cool for 2 minutes, then add the vanilla bean paste and give the marmalade a good stir. This is to ensure that your canned marmalade will have an even dispersion of peel/fruit and vanilla bean seeds.
• Divide the mixture between 5 or 6 sterilized jars (I prefer wide-mouth mason jars like these Ball jars on Amazon), leaving a headspace of 1/4 inch. If the 6th jar has a larger headspace, you are just going to have to eat it. Just kidding. Well, except that you can't seal it to store at room temperature, so that will be your jar to enjoy right away, storing it in the fridge. Wipe the rims of all the jars with a lightly moistened paper towel. Top each of the jars with a sterilized lid, and tighten the band until it is finger tight. The Ball canning kit on Amazon is key for this step and the next! Get it on Amazon
• Line a rimmed baking sheet with a large kitchen towel (these Nordic Ware sheet pans from Amazon are great). This will be the "cooling station" for the processed jars. To seal the jars, place them in a large pot, with a towel at the bottom to prevent them from rattling and cracking. Fill the pot with hot water so that the jars are completely immersed. Bring the pot of water to a boil with the lid on and once the boiling point has been reached, boil the jars for 5 minutes. Then take the pan off the heat, and let the jars stand in the pan for another 5 minutes. Finally, carefully remove the jars from the water bath and place them on the towel-lined baking sheet. You will hear a popping sound soon after, a good sign that the vacuum seal is proper. Let the jars cool, untouched, for 24 hours before putting them away.

GRAPEFRUIT MARMALADE

Steps:

• Sterilise the jars you'll be using to store the marmalade.Choose glass jars with an airtight, metal lid and ensure they have been washed in the dishwasher or by hand in hot soapy water then rinsed well.Check that the metal lids do not have rubber inserts. (See Note 9)Preheat the oven to 130 Degrees C (270 F) and place the jars in the oven for 15-20 minutes.
• Place 2 saucers or small plates in the freezer, ready to check for the setting point of your marmalade.Thoroughly wash the grapefruit and lemon. Remove each end of the grapefruit to get rid of excess pith. Remove each end of the lemon. Cut the grapefruit and lemon into quarters length ways. Holding two of the quarters together, slice as thinly as possible and remove any seeds.
• Place the citrus slices in a non-reactive bowl. See Note 4. Add the 6 cups of water, cover the bowl and leave the fruit to stand overnight, up to 24 hours. If your bowl is not large enough to accommodate all the water, add what you can and add the remainder the following day. It's best to make a note of what you have added.The following day, place the fruit and water into a very large, non-reactive saucepan. - See Note 5.
• Over medium-high heat, bring the fruit and water to the boil. Rapidly boil for approximately 15 minutes or until the peel is tender, stirring occasionally with a long-handled wooden spoon - See Note 6.
• Add the sugar and stir well to dissolve it. After dissolving the sugar, return the fruit to the boil, stirring occasionally. Continue to stir until the marmalade reaches setting point - I start to check at about 10 minutes. When the very aggressive bubbles subside to a slower, gentler boil, that's an indication that your marmalade may have reached setting point - See Note 7.Remove from the heat to conduct the wrinkle test. If not set, continue to boil for another 1 minute and then test again.
• To test for setting point, I use the "wrinkle" test. Take one of your saucers from the freezer and pour a small amount of marmalade onto it. Let it cool for a minute then push against the marmalade with the tip of your finger. If the surface wrinkles slightly, it means setting point has been reached.Alternatively, if you are not confident checking this way or are not experienced at making marmalade, you can use the fail-safe method of using a jam/candy thermometer which you clip to the side of your saucepan. When attaching your thermometer, make sure that the base is not touching the bottom of the saucepan. Your marmalade has reached setting point when the temperature reaches 104.5 degree C or 220 degrees F. (Taking it much higher than this will result in the marmalade being overboiled, the pectin being destroyed, and therefore, your marmalade will not set.)At this time, your marmalade will look very liquidy - it can take 24-48 hours to completely cool and set.Please note, this recipe will produce marmalade which has a soft set; it will not be as firm as many commercial varieties which often contain additives.
• Take the mixture off the heat. If there is any scum on the marmalade, add a teaspoon of butter and stir; that should settle the scum.
• Let the marmalade stand for about 10 minutes to allow the fruit to settle. If you bottle it immediately, the fruit will not be evenly distributed but will settle at the top of the jar.
• Remove your jars from the oven and carefully ladle the marmalade into the heated, sterilised jars. The jars should be filled as full as possible to minimise the amount of air between the marmalade and the lid. The marmalade should not touch the lid. Seal tight once filled with marmalade. See Note 8You need to be very careful. Splashing yourself with hot marmalade will result in a very serious burn. I suggest you have clothing with long sleeves and ensure that you do not have children nearby.

QUICK GRAPEFRUIT MARMALADE

Steps:

• Slice the grapefruit very very thinly with a sharp knife, into flat slices. then cut these into strips, and cut the strips into smaller bits. Keep all the juice that flows out, if it's a juicy grapefruit.
• Bring 6 cups of water to a boil, and then add the grapefruit slices and juice.
• Keep at a low boil, adding the sugar. Continue boiling for quite some time (20-30 minutes), until it begins getting thicker.
• The tricky part is knowing when to stop boiling. If you wait too long, it will become too thick when it cools. The important thing to know is it thickens a bit when cooling, so you have to stop it before it reaches the desired consistency. I put a porcelain dish in the fridge, then pour a little onto the dish - if it congeals a little, then it's ready.
• Before you bottle it, eat it with bread while it's still warm - it's delicious!
• Pour in any clean bottle, and refrigerate.

CITRUS MARMALADE

Steps:

• Cut the citrus: Using a sharp knife, slice off the top and bottom of the citrus so it sits sturdily on the cutting board. Slice off the peel and white pith in sections, starting at the top and following the curve of the fruit. (You should have a pile of peels and a few naked fruit.)
• Thinly slice the peels (with the pith) no thinner than 1/8 inch and no thicker than 1/4 inch, place them in a large bowl and set aside.
• Halve the fruit and remove any visible seeds. Thinly slice about 1/4-inch thick (white membrane and all), removing any seeds you might have missed. Add the fruit to the peels, and cover with 3 to 5 cups of water, taking note of how much water you used. Let this sit for at least 8 hours and up to 24 hours in the refrigerator. (This will help extract the pectin slowly as well as soften the peels.)
• Make the marmalade: Place a small plate in the refrigerator to chill. (You'll use this later.)
• Place the peels, fruit and water in a large pot. Add enough water to bring the total to 6 cups and bring to a strong simmer over medium-high heat.
• Cook the citrus until the peels have begun to soften and turn translucent, and the liquid has reduced by about three-fourths, 40 to 50 minutes.
• Add sugar and any add-ins and continue to cook, stirring occasionally at first, then more frequently as the marmalade cooks and the juices thicken. Continue until most of the liquid has evaporated and the peels are totally softened and almost completely translucent, another 40 to 50 minutes.
• As the marmalade cooks, the liquid reduces, the sugars thicken and the natural pectins activate. You'll notice the liquid go from a rapid, rolling boil with smaller bubbles to a slow, thick, tarlike boil with larger bubbles: This is the stage at which it's most important to stir constantly along the bottom of the pot to prevent scorching and sticking. (Sugar is heavier than water and will concentrate at the bottom of the pot, making the fruit more likely to burn.) It's also the stage at which splattering may occur, so take care in stirring.
• When the marmalade reaches this point, add lemon juice and continue to cook, stirring constantly until the jam has returned to its previously thickened state, about another 5 minutes. At this stage, the mixture should look thick and viscous with bits of the peel floating around. The peels will never break into the liquid as with a jam: This is O.K.
• To test the jam's thickness, spoon a bit onto the chilled plate, return it to the refrigerator and chill for 2 minutes. Drag your finger through it: It should hold its shape on either side without appearing watery or runny. If it's not there yet, cook it for a few more minutes.
• Remove from heat and discard the vanilla bean, if used. Divide among jars, leaving 1/4 inch of space at the top, and seal immediately. Can the marmalade (our How to Make Jam guide has detailed instruction), or store in the refrigerator.
