Understanding Mint

Mint is a versatile and aromatic herb prized for its culinary and medicinal uses. Its refreshing flavor and cooling properties make it a popular choice for both sweet and savory dishes, as well as for brewing teas and infusing oils.

Mint Varieties

Spearmint and peppermint are the two most common mint varieties used in cooking and canning. Spearmint has a milder, sweeter flavor ideal for culinary applications. Its leaves are bright green and slightly crinkled.

Peppermint, with its higher menthol content, offers a more intense, cool taste. It’s often used in candies, teas, and essential oils. Other mint varieties include apple mint, chocolate mint, and lemon mint, each with unique flavor profiles.

When selecting mint for jelly, choose fresh, vibrant leaves without blemishes or discoloration. The aroma should be strong and pleasant when rubbed between fingers.

Growing Your Own Mint

Mint is a hardy perennial that thrives in many climates. It prefers partial shade and moist, well-draining soil. Plant mint in containers to control its aggressive growth habit, as it can quickly overtake a garden.

Start mint from seeds, cuttings, or small plants. Water regularly and pinch back growing tips to encourage bushiness. Harvest leaves before flowering for the best flavor.

Mint is susceptible to rust and powdery mildew. Ensure good air circulation and avoid overhead watering to prevent these issues. Propagate new plants every few years to maintain vigor.

Growing mint at home ensures a constant supply of fresh leaves for jelly-making and other culinary uses.

Health Benefits of Mint

Proper preparation is crucial for safe and successful mint jelly canning. The right equipment and sterilization techniques ensure your jelly stays fresh and free from contamination.

Necessary Equipment

A boiling water canner is essential for processing mint jelly. This large pot with a rack keeps jars elevated during the canning process. Mason jars in 8-ounce sizes work well for mint jelly. New metal lids and screw bands are required for each batch.

Other necessary tools include:

  • Jar lifter
  • Canning funnel
  • Bubble remover tool
  • Magnetic lid wand
  • Clean cloth for wiping jar rims

A large stainless steel pot is needed for cooking the jelly. Tongs, measuring cups, and a ladle round out the equipment list.

Sterilization Process

Sterilizing jars prevents contamination and ensures food safety. Start by washing jars, lids, and bands in hot, soapy water. Rinse thoroughly.

Place clean jars in the boiling water canner. Fill with hot water to cover by 1 inch. Bring to a boil and process for 10 minutes.

Keep jars hot until ready to fill. Prepare lids according to manufacturer instructions. Some require brief boiling, while others just need hot water.

Sterilize all other utensils by boiling for 10 minutes or running through a hot dishwasher cycle. Keep everything clean and hot until use.

Mint Jelly Recipe

Making homemade mint jelly is a straightforward process that yields a delicious, versatile condiment. This recipe combines fresh mint leaves with sugar, pectin, and a few other ingredients to create a bright, flavorful jelly.

Ingredients List

  • 2 cups fresh mint leaves, tightly packed
  • 4 cups water
  • 5 cups white sugar
  • 2 tablespoons lemon juice
  • 1 box powdered pectin (approximately 1.75 ounces)
  • 4-5 drops green food coloring (optional)
  • 1/4 cup apple cider vinegar (optional, for a tangier flavor)

For a lower sugar option, replace 2 cups of the white sugar with Splenda or another sugar substitute. This will affect the set of the jelly, so adjust pectin accordingly.

Cooking Instructions


  1. Wash and finely chop the mint leaves.



  2. In a large saucepan, combine mint leaves and water. Bring to a boil, then reduce heat and simmer for 10 minutes.



  3. Strain the mint infusion through a fine-mesh sieve or cheesecloth. Measure 3 1/2 cups of the liquid.



  4. In a clean, large pot, combine the mint infusion, sugar, lemon juice, and pectin. If using, add cider vinegar now.



  5. Bring the mixture to a rolling boil over high heat, stirring constantly.



  6. Boil hard for 1 minute, continuing to stir.



  7. Remove from heat and skim off any foam.



  8. If desired, add green food coloring for a more vibrant appearance.


Timing and Temperature

Proper timing and temperature are crucial for jelly success. The jelly mixture should reach 220°F (105°C) at sea level. For every 1,000 feet above sea level, subtract 2°F from the target temperature.

Boil the jelly for exactly 1 minute after reaching a full rolling boil. Overcooking can lead to a stiff, rubbery texture.

After removing from heat, let the jelly cool for 5 minutes before pouring into sterilized jars. This helps prevent the mint from floating to the top.

Process filled jars in a boiling water bath for 10 minutes to ensure proper sealing and food safety.

Canning Process

Properly canning mint jelly ensures a safe, shelf-stable product. The process involves carefully filling jars and processing them in boiling water to create an airtight seal.

Filling Jars with Jelly

Sterilize canning jars and lids in boiling water before use. Ladle hot mint jelly into clean, hot jars, leaving 1/4 inch headspace at the top. Remove air bubbles by gently sliding a non-metallic utensil around the inside of the jar. Wipe jar rims with a clean, damp cloth to ensure a proper seal. Place lids on jars and screw on bands until fingertip-tight.

Sealing and Processing

Place filled jars in a boiling water canner, ensuring they are covered by 1-2 inches of water. Bring water to a rolling boil and process half-pint or pint jars for 10 minutes at sea level. Adjust processing time for higher altitudes. After processing, remove jars and let cool undisturbed for 12-24 hours. Check seals by pressing the center of each lid – it should not flex. Store properly sealed jars in a cool, dark place for up to 1 year.

Post-Canning Considerations

Proper storage and seal verification are crucial steps after canning mint jelly. These practices ensure the preserves remain safe and delicious for an extended period.

Storing Canned Mint Jelly

Store canned mint jelly in a cool, dark place. A pantry or cellar with temperatures between 50-70°F (10-21°C) is ideal. Avoid areas with temperature fluctuations or direct sunlight.

Label jars with the canning date. This helps track shelf life and ensures older jars are used first.

Properly canned mint jelly typically lasts 12-18 months. However, for best quality, consume within a year.

Keep jars clean and dry. Wipe off any residue before storing to prevent mold growth.

Testing for Proper Seals

Check seals 12-24 hours after canning. Press the center of each lid – it should not flex or pop.

Remove bands and lift jars by the edges of the lids. The lids should stay firmly attached.

Inspect for any signs of leakage or bulging lids, which indicate improper sealing.

If a jar fails the seal test, refrigerate and use within a few weeks. Alternatively, reprocess with new lids within 24 hours.

Master food preservers recommend periodically checking stored jars for any changes in appearance or odor.

Troubleshooting and Tips

Mint jelly can sometimes fail to set properly. If this occurs, add more liquid pectin and recook the jelly. For every 4 cups of jelly, use 1/4 cup sugar, 1 tablespoon lemon juice, and 2 teaspoons liquid pectin.

Straining the mint juice thoroughly is crucial. Use a fine-mesh strainer or cheesecloth to remove all plant particles. This ensures a clear, smooth jelly texture.

Avoid overheating mint leaves when extracting juice. Steep them in hot water for 15 minutes, then strain. Boiling can create a bitter taste.

For vibrant color, add a few drops of green food coloring. Natural mint juice often yields a brownish hue.

Use only fresh, unblemished mint leaves for the best flavor. Remove any damaged or discolored leaves before processing.

Store unopened jars in a cool, dark place for up to 1 year. Refrigerate after opening and use within 3 weeks.

If crystals form in grape-mint jelly, refrigerate the juice before making jelly to remove excess tartrate crystals.

Measure ingredients precisely. Altering sugar or pectin amounts can prevent proper setting.

Wipe jar rims clean before sealing to ensure a proper vacuum seal. Use new lids for each batch of jelly.
