Chocolate Orange Marmalade

Step 1

Before you begin, prepare calcium water. Todo this, combine ½ teaspoon calcium powder (in the small packet in your box ofPomona’s pectin) with ½ cup water in a small, clear jar with a lid. Shake well.Extra calcium water should be stored in the refrigerator for future use.

Step 2

If using glass jars, wash, rinse and heat them, either by filling them with water and heating in the microwave or by pouring warm to hot (not boiling) water into the jars. Keep the jars warm until ready to fill. Wash, dry, and set aside lids and screw bands. If using plastic freezer containers, wash and rinse.

Step 3

Zest all 4 oranges, ideally with a microplane, and set zest aside.

Step 4

Peel, section, remove any seeds, cut off any especially fibrous membrane or white pith, and chop oranges to yield about 2½ cups of chopped orange and juice.

Step 5

Chop chocolate into small pieces and set aside.

Step 6

Combine orange zest, chopped oranges, water, calcium water and lemon juice in a saucepan and mix well

Step 7

Measure sugar into a bowl. Thoroughly mix pectin powder into sugar. Set aside.

Step 8

Bring fruit mixture to a full boil. Add pectin-sugar mixture, stirring vigorously for 1 to 2 minutes to dissolve the pectin while the marmalade comes back up to a boil. Once the marmalade returns to a full boil, remove it from the heat and stir in the chocolate.

Step 9

Fill hot glass jars or plastic containers to ½” of top. Wipe rims clean. Screw on lids. Let jars cool. Marmalade will jell when it is completely cool (12 to 24 hours).

Step 10

If using plastic freezer containers, store marmalade in refrigerator or freezer once it is cool.

Step 11

If using glass canning jars, check to see if jars have sealed once the marmalade is cool. If so, you want to unseal them; then put the lids and bands back on before storing in the refrigerator or freezer. You don’t want to store this jam in a sealed jar since it hasn’t been tested for acidity.

Step 12

Eat refrigerated marmalade within 3 weeks. Eat frozen marmalade within 1 year. Lasts 3 weeks once thawed.
