- 3 cups water
- 3 yellow bell peppers, seeded
- 2 medium onions, peeled
- 1/3 cup sugar
- 1/3 cup cider vinegar
- 1 1/2 tablespoons frozen pineapple juice concentrate
- 1/4 teaspoon salt
- 1 serrano chile or jalapeno pepper, seeded and minced (optional)
- Put water on to boil in a medium saucepan.
- Meanwhile, shred peppers and onions with the large-hole side of a box grater into a large bowl. Finely chop any remaining pieces of onion or pepper and add them to the bowl. Cover with the boiling water and set aside for 10 minutes. Drain in a large colander for 5 minutes (don't squeeze out any moisture).
- Place the shredded vegetables, sugar, vinegar, pineapple juice concentrate, salt and chile (or jalapeno), if using, in a large saucepan. Bring to a simmer over medium-high heat, stirring occasionally. Reduce heat to medium-low and gently simmer until thickened and tender, 25 to 30 minutes. If the mixture gets too dry before the peppers are tender, add water, 2 tablespoons at a time. Refrigerate, uncovered, until chilled, about 2 hours.
