Homemade Maraschino Cherries

From The Garden of Eating.
Ingredients:
1/2 cup (125 ml) water
1/2 cup (125 ml) black cherry or concord grape juice
1/2 cup (4 ounces) natural cane sugar
Juice of 1 lemon (3 tablespoons/1 1/2 ounces/50 ml)
1/2 teaspoon pure almond extract
2 cups (9 1/2 ounces/266 grams) sweet bing cherries, pitted

1. Add the water, cherry or grape juice and sugar to a 2-quart pot. Bring to a boil over high heat and let cook 1 to 2 minutes until the sugar is completely dissolved. Reduce the heat to medium-low. Add the lemon juice, extract and cherries. Cook 5 minutes to let the cherries absorb the flavors, then remove the pot from the heat.
2. Transfer to a clean sterilized jar and process in a hot water bath for 10 minutes for long-term storage, or just put the jar in the fridge if you plan on using them within one month.
