Mirabelle-Rosemary Jam: A Taste of Sunshine

The first time I tasted mirabelle plums was in a tiny village in Alsace, France. I was cycling through the countryside, the late summer sun warm on my skin, and stopped at a roadside stand overflowing with these golden orbs. The farmer insisted I try one, and the burst of sweet-tart juice was like sunshine in my mouth. I bought a basketful, and the memory of that day—the sun, the plums, the scent of rosemary drifting from a nearby garden—has stayed with me ever since. This jam is my attempt to capture that feeling, a little jar of sunshine and memories.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 4 minutes
• Total Time: 30 minutes
• Yields: 3-4 glasses (approx. 200ml each)
• Dietary Type: Vegetarian, Gluten-Free

Ingredients

• 720 g yellow plums (mirabelles), pitted (weight after pitting)
• 240 g super gelling sugar (Dr. Oetker’s 3:1)
• 4 sprigs fresh rosemary (each about 2 inches long)
• 2 tablespoons lime juice
• ½ vanilla bean

Equipment Needed

• Food processor (or potato masher)
• Large pot
• Sterilized jars with lids
• Spoon
• Knife
• Cutting Board

Instructions

1. Begin by preparing the mirabelles. Wash the yellow plums thoroughly and pit them. This is a crucial step, as the pits will ruin the texture of the jam. Weigh out 720 grams of the pitted fruit.
2. Next, puree the mirabelles to your desired consistency. I prefer a slightly chunky jam, so I use a food processor and pulse the fruit until it’s partially mashed, but you can also use a potato masher if you prefer a rustic texture.
3. Transfer the mirabelle puree to a large pot. Add the super gelling sugar (240 grams) and mix well to ensure the sugar is evenly distributed. This type of sugar already contains pectin, which helps the jam to set properly. If you cannot find Dr. Oetker’s 3:1 gelling sugar, you could also use Dr. Oetker’s 2:1 super gelling sugar (then use 360 g sugar) and follow the instructions on the package, or another brand of gelling sugar following their directions.
4. Prepare the vanilla bean. Cut the vanilla bean in half lengthwise and scrape out the seeds. Set the seeds aside.
5. Add the vanilla bean halves and the rosemary sprigs to the fruit mixture. These aromatics will infuse the jam with their wonderful flavors.
6. Bring the mixture to a boil over medium-high heat, stirring constantly. This prevents the jam from sticking to the bottom of the pot and burning.
7. Once the mixture is boiling vigorously, cook for 4 minutes, stirring continuously. This is a critical step to activate the pectin in the sugar and ensure the jam sets properly. Be sure to use a timer to ensure accurate timing.
8. Remove the pot from the heat. Take out the rosemary sprigs and the vanilla bean halves. They have done their job of infusing the jam with flavor.
9. Stir in the lime juice (2 tablespoons) and the vanilla seeds. The lime juice adds a touch of acidity that balances the sweetness of the mirabelles, while the vanilla seeds provide a delicate, floral aroma.
10. Fill the hot jam into prepared, sterilized twist-off preserving jars. Leave about ¼ inch of headspace at the top of each jar.
11. Close the jars tightly with their lids. Let the filled jars stand for 1 minute, then turn them upside down. Let them stand upside down for 10 minutes, then turn them right side up again. This helps to create a vacuum seal. This process is not essential but some swear by it.
12. Let the jars cool completely at room temperature. As the jam cools, it will thicken. You should hear a “pop” sound when the lid seals, indicating a successful seal.

Expert Tips & Tricks

• Sterilize your jars properly: This is crucial for preventing spoilage. Wash the jars and lids in hot, soapy water, then boil them for 10 minutes. Alternatively, you can run them through a hot cycle in your dishwasher.
• Use a candy thermometer (optional): If you prefer a more precise method of checking for doneness, use a candy thermometer. The jam is ready when it reaches 220°F (104°C).
• Adjust the sugar: If your mirabelles are particularly tart, you may want to add a little more sugar to taste.
• Don’t overcook: Overcooking the jam can result in a tough, rubbery texture.
• Test for set: If you’re unsure whether the jam is ready, place a small spoonful on a chilled plate. If it wrinkles when you push it with your finger, it’s ready.

Serving & Storage Suggestions

This Mirabelle-Rosemary Jam is delicious spread on toast, scones, or croissants. It also pairs well with cheese, particularly creamy goat cheese or brie. Serve it alongside grilled meats or use it as a glaze for roasted vegetables.

Store the sealed jars of jam in a cool, dark place for up to one year. Once opened, store in the refrigerator for up to 2-3 weeks. Properly sealed jars stored in a cool, dark place may last longer, but it is best to check for any signs of spoilage before consuming.

FAQs (Frequently Asked Questions)

Q: Can I use frozen mirabelles for this recipe?
A: Yes, you can use frozen mirabelles. Thaw them completely before using and drain off any excess liquid. This may slightly alter the cooking time.

Q: Do I really need to use super gelling sugar?
A: Yes, super gelling sugar is recommended to ensure the jam sets properly. It already contains pectin, which is essential for thickening the jam. If you can’t find the 3:1 type, be sure to adjust the amount of regular sugar based on package directions of the pectin.

Q: How do I know if the jars are properly sealed?
A: After cooling, press down on the center of the lid. If it doesn’t flex or pop back up, the jar is properly sealed. If it flexes, the jar didn’t seal correctly and should be stored in the refrigerator and consumed within a few weeks.

Q: Can I double or triple this recipe?
A: Yes, you can double or triple the recipe, but be sure to use a large enough pot to prevent the jam from boiling over. You may also need to increase the cooking time slightly.

Q: Why is my jam not setting?
A: There are several reasons why your jam might not set. It could be that you didn’t cook it long enough, that you didn’t use enough sugar or pectin, or that your fruit was too ripe. Next time, try cooking it longer, adding more sugar or pectin, or using less ripe fruit.
