Here in California, blood oranges are only available in the winter -- they show up in our groceries as early as Thanksgiving but more typically around New Years and they're only around till early March. I drive Jen crazy by filling up our fridge with bags of the suckers wanting to make all sorts of things with them (cakes, tarts, curds, ice cream, & marmalade).
Here's my take on making the marmalade based on the recipe from the Ball Complete Book of Home Preserving.
Blood Orange & Lemon Marmalade
This makes around six 8 oz. jars
3 lbs Blood
Oranges (around 8)
2 big or 3 small Lemons
4+ cups Water
6 cups Sugar
8 tsp Grand
Marnier
A. Prep peel
1. Using a sharp knife or
vegetable peeler, cut the colored part only from the oranges and lemons.
2. Avoid getting the bitter
white layer
3. Place peels in a saucepan
generously covered with cold water.
4. Bring to a boil over
medium-low heat
5. Boil for 10 minutes.
6. Drain.
7. Again, generously cover
with cold water and return to a boil.
8. Boil for 10 more minutes
until the peel is softened.
9. Drain.
10. Cut peel into paper thin
strips
Alternate
method to 1-10 : use a Microplane
to zest the fruit -- avoid getting the bitter white layer
B. Prep fruit
1. With a sharp knife, cut and
set aside the remaining peel and membrane from the oranges and lemons.
2. Thinly slice the oranges
and lemons, setting aside any tough pith or seeds
3. Roughly chop the fruit --
be sure to save all the juice
4. Place the reserved peel,
membrane, pith, & seeds (from steps 1 & 2) in a cheesecloth bag
C. Cook the fruit -- Part 1
1. Put chopped fruit, peel,
cheesecloth bag and 4 cups water in a saucepan
2. Bring to a boil over
medium-high heat
3. Reduce heat and boil
gently, stirring frequently for around 30 minutes until peel is very soft when
squeezed with fingers
4. Remove from heat
5. Take cheesecloth bag and
squeeze out as much natural pectin as possible over a separate bowl and then
add this back to the fruit
6. Puree in blender or food
processor
7. Measure out 6 cups of the
fruit mixture
8. Add more water to get a
total of 6 cups
9. Mix well
NOTE: Prepare canner, jars, and lids now
D. Cook the fruit -- Part 2
1. Ladle all 6 cups of cooked
fruit into a clean, large, deep saucepan.
2. Bring saucepan to a boil
over medium-high heat.
3. Maintaining boil, gradually
stir sugar into pan.
4. Boil hard stirring
constantly until the mixture reaches the gel stage, about 15 - 18 minutes
5. Just before gel stage, add
Grand Marnier to saucepan
6. Remove from heat and test
gel.
7. If gel stage has been
reached, skim off foam.
E. Canning the fruit
1. Ladle hot marmalade into
hot jars, leaving 1/4 inch headspace
2. Remove air bubbles and
adjust headspace, if necessary by adding hot marmalade
3. Wipe rim
4. Center lid on jar
5. Screw band down until
resistance is met, then increase to fingertip-tight
6. Place jars in canner,
insuring that they are completely covered with water.
7. Bring to a boil and process
for 10 minutes.
8. Remove canner lid
9. Wait 5 minutes
10. Remove jars, cool, and
store.
